英国Exeter大学博士招生（全额奖学金） China Scholarship Council and University of Exeter PhD Scholarship Ref: 2817 About the award The University of Exeter is proud to offer up to 10 full-time PhD scholarships in collaboration with the China Scholarship Council (CSC) for Chinese students starting in the academic year 2018-2019. The University of Exeter combines world-class research with high levels of student satisfaction at its campuses in Exeter and Cornwall, South West England. Formed in 1955, the University has over 21,000 students from more than 130 different countries. Exeter has been a leader in cutting-edge science, engineering, mathematics and medicine research and 98% of our research has been rated as of international quality. For more information please see our CSC webpage. (https://www.exeter.ac.uk/chinascholarship) Scholarships are available for study in the following subject: College of Engineering, Mathematics and Physical Sciences (CEMPS) Physics and Astronomy Eligibility 1. Applicants must be citizens or permanent residents of the People's Republic of China at the time of application and intend to return to China upon completion of their studies at the University of Exeter. 2. The scholarship will be awarded on the basis of academic merit with candidates requiring the equivalent of a Distinction in a UK Masters degree from a prestigious university (Typically an average of 85% or above from a Chinese Higher Education Institution). 3. Successful candidates will meet the relevant academic requirements as well as the English language proficiency requirements for entry into a PhD programme set out by the University of Exeter. Applicants are generally expected to have a score of IELTS 6.5 – 7.0 or equivalent overall with no less than 6.0 in any section. More information can be found here: https://www.exeter.ac.uk/postgraduate/apply/english/ 4. Candidates will also be required to satisfy the selection criteria set out by CSC. Details can be found on the website: China Scholarship Council. Funding Full tuition fees of successful applicants will be funded by the relevant College at the University of Exeter. The China Scholarship Council will provide a living allowance, including the cost of a return flight from China to the UK, accommodation and subsistence, depending on the applicant's eligibility. https://www.exeter.ac.uk/studying/funding/award/?id=2817 https://www.exeter.ac.uk/studying/funding/award/?id=2817 Project description: Probing Spin Effects in Two-Dimensional Materials Similar to Graphene Supervisors Main supervisor: Dr Annette Plaut Co-supervisor: Prof Mikhail (Misha) Portnoi The possibility of using the spin of electrons to achieve faster and more energy efficient electronic devices is a central concept of spintronics and thus spintronic effects are interesting from the perspective of quantum computing. However the lack of an effective means for the successful generation, manipulation and electrical detection of the electron spin within semiconductors remains an outstanding challenge. Graphene is a two-dimensional honeycomb structure of carbon atoms. However due to the small size of the carbon atom, graphene does not exhibit measurable spintronic effects. Instead graphene is now being superseded by other twodimensional materials such as the transition metal dichalcogenides, where the honeycomb lattice is made up of, for instance, a combination of a transition metal atom and two sulphur or selenium atoms. The larger inherent spin-orbit interaction in such transition metal dichalcogenides, due to the large size of the transition metal atom, combined with their crystal inversion asymmetry – unlike graphene – make spintronic effects detectable in these new two-dimensional materials. Spin-orbit coupling is the most fundamental spin-dependent interaction in nonmagnetic semiconductors. It is a relativistic effect that couples the charge-carrier spin to its orbital momentum. In the spin Hall effect, on passing a current through the sample, the spin-orbit interaction drives the charge carriers with up and down spins to opposite sides of the sample. Here it is the intrinsic spin-orbit coupling that causes the charge carriers to move transverse to the current, rather than an external magnetic field as in the classical Hall effect. However the spin Hall effect is not electrically detectable due to the charge-balanced nature of its transverse spin currents. But by optically polarizing the charge carrier spins, the transverse current becomes charge-imbalanced and a Hall voltage can be measured in the absence of a magnetic field. This University of Exeter/China Scholarship Council PhD studentship will fund you to investigate manifestations of the spin Hall effect, and also the closely-related valley Hall effect, via such optically-polarized phototransport techniques. You will search for the elusive spin Hall effect in these two-dimensional materials and confirm the tentative evidence for the existence of the valley Hall effect. You will also be the first ever to measure the carrier-density dependence of such photo-induced voltages. The valley Hall effect arises due to the bandstructure of such two-dimensional materials possessing two unequal valleys at the Dirac points. The spin polarization of the charge carriers is coupled to the valley in which they reside. It is theoretically predicted that photoexcitation of the charge carriers with linearly-polarized light will result in the carriers belonging to the two different valleys moving in opposite directions. This you will detect purely optically, by measuring the spatial distribution of the circularly-polarized photoluminescence in two-dimensional materials. https://www.exeter.ac.uk/studying/funding/award/?id=2817 https://www.exeter.ac.uk/studying/funding/award/?id=2817 During your PhD you will join the vibrant Exeter University Graphene Centre encompassing state-of-the-art facilities and training opportunities providing you with a wide variety of highly employable skills and techniques. Summary Application deadline: 29th January 2018 Value: Full tuition fees and Living Allowance Duration of award: per year Contact: Annette Plaut (A.S.Plaut@exeter.ac.uk) How to apply Stage One – Apply to the University of Exeter In the application process you will be asked to upload several documents. Please note our preferred format is PDF, each file named with your surname and the name of the document, eg. “Smith – CV.pdf”, “Smith – Cover Letter.pdf”, “Smith – Transcript.pdf”. • CV • A research proposal • Letter of application outlining your academic interests and prior research experience. • Transcript(s) giving full details of subjects studied and grades/marks obtained. This should be an interim transcript if you are still studying. • Evidence of your English language proficiency. You will be asked to name 2 referees as part of the application process, however we will not contact these people until the offer stage. Your referees should not be from the prospective supervisory team. Apply here for College of Engineering, Mathematics & Physical Sciences (https://srs.exeter.ac.uk/urd/sits.urd/run/siw_ipp_lgn.login?process=siw_ipp_app&code1=ECSRDFA4Y6&code2=0008) The closing date for this application is midnight on 29th January 2018. CSC will be notified of the fee waiver with a copy of the offer letter. Stage 2 – Apply to China Scholarship Council (CSC) Successful applicants will need to apply for CSC funding following the guidelines specified by the China Scholarship Council.
