Training in: Development, optimization and use of tight binding based electronic structure codes, multiscale-coupling with continuum model device simulation tools, device modelling and simulation.

Reliable and efficient electronic structure calculations are a mandatory prerequisite for analysis and design of nanostructures. Atomistic models like empirical tight binding (ETB) have proven particularly useful for the simulation of nanostructures and disordered alloys. Successful application of atomistic models in device simulation requires adequate model parameterizations, efficient solvers and coupling with continuum based device TCAD software.

The research will focus on further development of an ETB code.  A tool for generation of reliable parameter sets and improved methods for including mechanical strain will be implemented. Efficiency of the numerical solution strategies shall be improved, and suitable linking with continuum device models has to be further developed. The developed tools will be used to simulate relevant III-Sb devices.

Existing codes for empirical tight binding and parameter generation will be further developed and optimized. Parameter generation based on optimization strategies will be improved and generalized. Improved ways to include strain in the atomistic tight binding described in literature model will be evaluated and implemented. The numerical efficiency of the tight binding code will be improved by optimizing the built-in solvers or by linking to existing parallelized libraries. Efficient strategies for the multiscale coupling with existing device TCAD software will be developed.

Environment

Institution: The University of Rome Tor Vergata has been founded in 1982. It counts 18 departments, 2300 employees and 35000 students, and has a strong international orientation.
Institute/Laboratory: The Nano & Optoelectronics Group (OLABs) is part of the Department of Electronic Engineering. The group is working both in theory and simulation of electronic devices from the atomic to the device scale, and in development and characterization of organic and hybrid optoelectroncis. OLABs has around 25 PhDs and PostDocs in a strong international setup.
Location/City: The university campus is located south-east just outside the highway ring of Rome, Italy, and is easily reachable by metro and bus.
