[交流] 博士位置全奖英国 Heriot-Watt University

帮师兄发个位置，在Heriot-Watt University，学校排名一般，但是师兄能力很强，很学术（发过3篇一作的 nature communications，），人也很好，30多岁，是做事的年龄。比很多只是搞management 教授好很多，跟他能学到东西。位置是偏光学和微加工的。师兄想要个微加工方面动手能力强的，因为idea很多，但是有时候实践中不容易做出来。位置的具体信息如下。有兴趣的就申请哈。

JWS2014/14: Active ultrathin optoelectronic devices with novel materials

Optical metamaterials and a new class of two dimensional materials (e.g. graphene and transition metal dichalcogenides) have captured the attention of the scientific community due to their unusual electronic and optical properties, which provide new opportunities to develop ultrathin optoelectronic devices with novel functionalities. This project aims to expand our recent findings in developing ultrathin metadevices (e.g. dual-polarity metalens, broadband vortex beam generator) into a viable research programme by combining metamaterials and new two-dimensional materials.

You might be a potential candidate if you are interested in both photonics and nanofabrication. A James-Watt Scholarship is available in the School of Engineering and Physical Sciences at Heriot-Watt University (Edinburgh, UK), supervised by Dr. X Chen, to develop novel optical metamaterials and their applications in imaging and information processing.

Metamaterials are man-made materials which have unusual electromagnetic properties that may not be found in nature or their constituent components. Benefiting from the freedom in tailoring electromagnetic properties, various metamaterials have been developed to enable some ground-breaking applications, such as invisibility cloaking, super-imaging and negative refraction. Metasurface, an emerging field of metamaterials that consists of only a monolayer of planar metallic structures, have shown great promise for controlling light propagation, while keeping fabrication cost low, as they do not require complicated three-dimensional nanofabrication techniques. Unlike the phase change by the accumulated optical path in traditional optical elements, the abrupt phase change takes place at the interface when a linearly polarized incident light is converted to its cross polarization or a circularly polarized light is converted to its opposite helicity. Metasurfaces can provide the desired phase discontinuities, which have been experimentally demonstrated in novel metadevices such as broadband vortex beam generator, 3D optical holography, ultrathin dual-plarity metalenses and polarization dependent unidirectional surface plasmon polariton excitation. As a new field of metamaterials, there are a lot of exciting phenomena and unusual prototype devices waiting for you to explore. You are welcome to visit this webpage (http://www.eps.hw.ac.uk/staff-directory/x-chen.htm) if you want to know more about our research.

We are looking for a highly motivated candidate with a strong experimental background in the following related areas: plasmonics, nanophotonics, metamaterials or grapheme related research.  Experience in using cleanroom and nanofabrication facility is desirable. Commonly used nanofabrication facilities such as electron beam lithography, focused ion beam, etcher and evaporator for film deposition are available in the school. Experience in CST microwave studio, COMSOL Multiphysics and math tools such as Matlab will be a plus. This project will be supervised by Dr X Chen and Prof. B. D. Gerardot (http://gerardot.eps.hw.ac.uk/). During this studentship you will be exposed to a wide range of exciting areas including nanophotonics, optical metamaterials, plasmonics, optical design and nanofabrication. The ultrathin planar metadevices you develop will be directly used in imaging and information processing.

Informal academic enquiries should be directed to Dr Xianzhong Chen (x.chen@hw.ac.uk), with a copy of your current CV, cover letter and two reference letters. All general enquiries should be directed to the Postgraduate Admissions Office (pgadmissions@hw.ac.uk).
