Researcher in Surface characterization of hybrid semiconductor/metal nanostructures - Hiring in process/Finished, not possible to apply

The Division of Synchrotron Radiation Physics (www.sljus.lu.se) is a part of the Department of Physics and has more than 50 employees. The focus of the research is experimental studies of electronic, structural and chemical properties of materials, accelerators for Synchrotron radiation and instruments and methods for Synchrotron radiation. At the Division we use and develop a wide range of Synchrotron- and lab-based techniques, such as X-ray photoelectron spectroscopy/imaging and X-ray diffraction/imaging. We also host one of Sweden's largest facilities for scanning probe microscopy. We are additionally engaged in the development of the MAX IV Laboratory in the fields of beamlines, experimental stations, techniques for Synchrotron radiation and the accelerator systems.

Subject description
An interesting topic in nanomaterial science is the hybrid combination of materials such as III-V semiconductors and Graphene. In order to rationally design devices from these structures the combined manufacturing as well as their electronic, chemical and optical properties studied. In nano-objects, surfaces and interfaces are of particular importance, as they often directly define device functionality and strongly influence local electrostatics and strain fields.

This project aims to study the combination of III-V nanowires and graphene using cutting edge scanning tunneling microscopy/spectroscopy (STM/S) and the highly advanced Lund III-V semiconductor nano-device platform. In addition, synchrotron based spectromicroscopy will be used. The aim is to explore and understand the fabrication and function of novel nanoscale devices for electronics, photonics and quantum technologies based on novel material combinations. A focus is on surfaces and interfaces of nanoscale objects, which are of particular importance, as they often directly define functionality. While an emphasis will be on III-V nanowire heterostructures in combination with Graphene, other studies of material adsorption and devices based on III-V nanowires will be considered. 

The research group has access to six fully functioning ultrahigh vacuum STM/AFM systems, several of which are equipped with electrical contacts for in-situ studies of electronic devices and one (newly acquired) also operates at below 10K. Results obtained at the MAX IV Laboratory in Lund, the world’s most brilliant synchrotron facility (www.maxiv.lu.se), as well as at other international synchrotrons will also be involved.

Work duties
The successful candidate is supposed to perform research within the subject area. More specifically, the work duties include:

• Development and studies of combined Graphene/III-V nanowire samples.
• Performing and analyzing STM/S experiments on III-V nanowires and devices
• PEEM/LEEM and other photoemission studies of the above mentioned samples.

This work will be embedded in the NanoLund (www.nano.lu.se) Center for Nanoscience. The successful candidate will interact with experts in manufacturing of semiconductor nanoscale structures and devices to design relevant structures. The work will be performed in collaboration with several other researchers at the institute as well as a number of Ph.D. students and master students.

Qualification requirements
Applicants must have:

• A PhD or equivalent research qualification within the subject of the position.
• Very good oral and written proficiency in English.
• Hands-on experience in scanning tunneling microscopy and spectroscopy at both room and low temperature
• Hands-on experience in working with both Graphene and III-V semiconductor nanowires

Assessment criteria and other qualifications
Particular emphasis will be placed on research skills within the subject and on previous experience that helps to perform the described work duties.

Consideration will also be given to good collaborative skills, drive and independence, and how the applicant’s experience and skills complement and strengthen ongoing research within the department, and how they stand to contribute to its future development.

Terms of employment
This is a full-time, fixed-term employment of 12 months. Preferred start date is XXX.
