[交流] 2017年第二轮中德博士后联合奖学金项目（27个岗位共22份联合奖学金）已有11人参与

博管办与亥姆霍兹联合会的中德博士后联合奖学金共约定50个待遇优厚的奖学金项目，在前一轮只收集到50个申请人通过正规的途径即博士后工作站投递申请材料，其中29人通过评审。因为与50份奖学金的差异较大，经双边商量，额外设置了今年的第二轮申请人征集，除了在第一轮中没有获得申请人，或者导师仍然有犹豫不能最后确认成功申请人的岗位之外，也投放了个别新的岗位。其中，也包括下面这个KIT05岗位，第一位入选者因为另有美国的全额博士后而放弃；第二位入选者因为个人身体原因而放弃，另外的两位申请人不能令导师满意，因此而继续开放，期待理想中的申请人出现。

Call of the KIT 05 position
Helmholtz–OCPC Programme 2017-2021 for the Involvement of Postdocs in Bilateral Collaboration Projects with China
partly funded by the
Office of the China Postdoctoral Council (OCPC)
of the Ministry of Human Resources and Social Security (MoHRSS)

Part A Project Title: Shape Memory Nanoactuators for Nanophotonic Devices
Karlsruhe Institute of Technology, Institute of Microstructure Technology (IMT)
Contact: Prof. Dr. M. Kohl,
E-mail: manfred.kohl@kit.edu,

Research Topic:
This research focuses on novel integrated actuators based on shape memory alloys (SMAs) with nanoscale dimensions for control of optical signals in silicon waveguide structures.
Miniaturization and integration of SMA actuators in nanoscale systems is motivated by their large work output in the order of 107 Jm-3 enabling ultra-small layouts. One example is the ferromagnetic SMA NiMnGa that exhibits outstanding actuation properties in bulk shape, such as thermo-elastic and magneto-strain effects up to 12%. Using these effects at the nanoscale opens up a new generation of mechanically active devices having switching and tuning capability. Here, target applications are adaptive silicon photonic devices that are expected to provide substantial size and cost reduction compared to traditional optical solutions in communication technology. In previous work, free-standing SMA-Si bimorph cantilever actuators with lateral dimensions of 200 nm have been developed showing actuation based on superimposed shape memory and bimorph effects. This technology will be further down-scaled to lateral dimensions below 100 nm and combined with Si waveguide technology. The thermo-mechanical and optical properties of mechanically active Si photonic devices will be investigated by finite element (FE) simulations and in-situ measurements.

The research topic includes the following tasks:
- Characterization of SMA material properties (SEM, XRD, DSC, tensile experiments,DIC...)
- Development / optimization of nanofabrication technologies
- Finite element simulations (multiphysics), modeling of optical wave propagation
- Design, fabrication and characterization of Si photonic demonstrator systems
This research has a pronounced interdisciplinary character covering different fields of
materials science, mechanical and electronic engineering. For fabrication, the IMT operates
a state-of-the-art cleanroom facility including electron beam lithography, physical vapor
deposition and reactive ion etching. Furthermore, IMT is part of the Karlsruhe Nano Micro
Facility (KNMF) at KIT providing free access to multi-material state-of-the-art micro and
nanotechnologies. Advanced simulation tools and measurement equipment are available for
investigation of device performance.

Cooperation:
IMT is seeking for new collaboration(s) with one or several research groups at China’s top
elite universities at the interface of smart materials research, nanotechnology and photonics.
The demanding and interdisciplinary nature of the research topic requires expertise from the
fields of materials science, physics and engineering. The postdoctoral candidate(s) will be
integrated into a running project at IMT in order to establish an international collaboration
of researchers with complementary expertise and common interest in translating basic
science and new technology into photonics applications.
Requested qualification:
Background in materials science, mechanical and electrical engineering, cleanroom
technologies; experience in FEM simulation is of advantage
Part B of the form contains the documents to be submitted by the postdoc to the
OCPC and can be supplemented and modified by the project leader
depending on the project proposal.
 Reason for the candidate's personal interest in a research visit to KIT
 CV and copies of certificates
 List of publications
 Two letters of recommendation
 Evidence of competence in English
Part C of the form describes the conditions of the programme which must be
observed by the postdoc.
 Completion of PhD within the past five years
 Not older than 35 years at the time of application
