PhD scholarship in van der Waals Heterostructure Devices

jobbeskrivelse:
The project concerns study of the electrical properties of two-dimensional materials such as graphene and transition metal dichalcogenides (TMD). You will learn to fabricate devices using our “hot pickup” dry transfer method to create ordinary van der Waals heterostructure devices and to integrate pre-patterned layers in complex 2D/3D heterostructures. You will explore and optimise key technological issues such as contact resistance, gate leakage and hysteresis for ultrathin gates, contamination and blisters and more, and based on this fabricate and characterise high quality device prototypes (electronics and optoelectronics). The project will be carried out in within the European project Graphene Flagship and the Centre for Nanostructured Graphene. Responsibilities and tasks We offer a 3 year PhD position to perform research in the following areas: •Fabrication of clean, high performance graphene and TMD devices and optimization of contact resistance, gate quality and room temperature performance. •Fabricate working prototypes of ballistic switches, transistors and/or optoelectronic devices, and characterising their properties •Electrical characterization and comparison with theoretical predictions at room and cryogenic temperatures •Effects of nanopatterning and device processing on electrical characteristics •Scaling up of van der Waals assembly method. Qualifications Candidates should have a master's degree in engineering or a similar degree with an academic level equivalent to the master's degree in engineering. Approval and Enrolment The scholarships for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide. Assessment The assessment of the applicants will be made by consideration of relevant, documented experience and competences, here in particular: •Graphene or TMD device fabrication •Room and/or low temperature transport measurements on mesoscopic or graphene devices •Nanopatterning / Electron beam lithography •Relevant characterisation techniques (Raman spectroscopy, SEM, TEM, AFM, FTIR). •Device physics (electronic properties of graphene, 2D materials and van der Waals structures. Role of disorder, doping and contact resistance). We are looking for a student strong in experimental physics, who is creative, fast-learning, independent, hard-working and function well in a team. We will also take into account the past performance in relevant courses (solid state physics, quantum mechanics, transport theory, computational physics, electronics, materials science). It may also be taken into account how soon you can start. We offer We offer an interesting and challenging job in an international environment focusing on education, research, public-sector consultancy and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world. Salary and appointment terms The salary and appointment terms are consistent with the current rules for PhD degree students. The period of employment is 3 years. Further information Further information may be obtained from Professor Peter Bøggild, peter.boggild (at) nanotech.dtu.dk. The project will be co-supervised by Professor Kristian Thygesen, DTU Physics and assistant professor Nicolas Stenger, DTU Fotonik.
