PhD student position (f/m/d) in Diamond Semiconductor Physics
PhD student position in Diamond
Currently, we have opened a PhD-student vacancy in the Diamond Electronic Group at the
division of Electricity, Dept. of Electrical Engineering, Uppsala University.
The position is within the field of diamond semiconductor devices, solid state physics and
electronic and spintronic properties of CVD diamond. Diamond possess extreme material
properties and in particular many extreme properties as a semiconductor. It is now possible to
manufacture films of high purity single crystalline diamond, which opens up the possibility to
utilize these properties in future electronic and spintronic devices.
About the division: The Division of Electricity at the Department of Engineering Sciences,
Uppsala University conducts research on electromagnetics, power electronics and renewable
energy. The diamond group has a proven track record working on cutting-edge semiconductor
technology with a number of publications in high impact journals.
Project description: The attractive material properties of diamond such as high band gap, high
carrier mobilities, high thermal conductivity, high breakdown field strength, radiation
hardness, etc., make it a very interesting semiconductor material. Recently, diamond has
received great attention for applications in spintronics and valleytronics. This is because of the
unique quantum mechanical properties of diamond, as well as the presence of defects, e.g. the
N-V center, with extremely long spin coherence time.
Diamond is considered to be a unique material for future high power, high frequency, high
temperature devices like high-power Schottky diodes, MESFETs etc for applications in power
electronics, fast switching transistors and for spintronics. Designs and fabrication techniques
different from conventional methods have to be employed to realize electronic devices based
on thin film single crystalline chemical vapour deposited (SC-CVD) diamond. Diamond also
has a huge potential to be used as detectors in high energy physics, detectors for UV and far
UV radiation, radiation sensors for radiotherapy, neutron detectors etc.
Duties: The proposed work consists of:
Fabrication and characterization of spin- and valleytronic test devices in diamond
and growth of graphene films on diamond substrates using state-of-the-art optical
and electrical characterization techniques.
Modelling and computer simulations of devices.
Material characterization of CVD diamond by various characterization techniques
and improving methods for studying transport processes in diamond.
PhD positions in Sweden are usually of 4-5 years duration. The student will have the
opportunity to attend courses from the graduate curriculum within the fields of Solid state
physics, Semiconductor device technology, Material physics, etc. PhDs are also expected
to do some teaching, in Swedish or English, approximately 20% of full time. www.teknik.uu.se
Requirements: We are looking for a strong candidate with a Master degree in physics,
semiconductor physics or material physics with some experience in one or more of:
Solid state physics
Semiconductor device physics
Semiconductor material characterisation
Micro/Nano structures & technology
We also require high level of proficiency in English.
