The project is aimed to provide the student the basic knowledge of Density Functional Theory (DFT) and Non Equilibrium Green's Function (NEFF) method. They represent the state-of-art of modeling for numerical simulations in vibrational,optical, and electronic properties and transport properties of functional devices, respectively.To obtain accurate results and predict the characteristics of not-yet-fabricated structures, DFT and NEGF must be combined with each other, the former provides the Hamiltonian and Hessian matrices that the latter needs. The project will focus on thestudy of ballistic thermal properties of 2D Transition metal dichalcogenide (TMDs), such as MoS2. The software involved in this project will be the DFT tool Quantum ESPRESSO and VASP as well as the device simulator OMEN.

==The Big Picture ==
 
−
Integrated electronics constitute one of the most important and spread aspects of our everyday life and among the years the size shrinking of transistors, the active component of all integrated circuits, has been supported and encouraged by several aspects. Obviously, in order to improve the performances of devices, the indefinitely reduction of dimensions  can not be the only prospective, but it must be combined with the research of new channel materials able to replace Silicon. Here, the quantum confinement plays a fundamental role, since it has been demonstrated that it significantly affects the properties of nano-sized materials with respect to their bulk counterparts. The simulations will focus on Transition Metal Dichalcogenide(TMDs), which  consist of one layer of a transition metal sandwiched between two chalcogen layers. Single-layers of TMD have received a wide attention following the the demonstration of a properly working MoS2 transistor. The final goal would be to found trends able to make the research more target-oriented and less hazarous.

Background

Over the years, we developed a unique technology to bring a material with extremely strong Pockels coefficients into a scalable silicon photonic platform. Having such physical effect available in integrated photonics circuits has been a scientific and technological breakthrough, which enables the realization of advanced photonic structures and completely new applications, e.g. for photonic AI networks and quantum computing. At Lumiphase, we are bringing this new technology to market, while at the same time developing new scientific and technological concepts. The internship project is placed in the heart of our R&D activities and covers topics related to optical design and simulations, having the designs fabricated, and perform photonic characterization on them.

Details about the project

During this master or internship project, you will work in tight interaction with the Lumiphase R&D team to develop a waveguide-based, passive photonic component in an advanced, integrated photonic platform. You will perform theoretical and practical work, giving you a broad background into industrial driven R&D activities in the field of integrated photonics for optical communication. The work during the internship is technology driven, and includes

Simulations of photonic structures using advanced simulation tools (e.g. COMSOL, Lumerical, …)
Generation of photonic mask designs
Performing optical measurements using fiber-optical characterization setups and photonic chips fabricated by the

Lumiphase team

Analyzing experimental data, including the development of scripts, data visualization, and error analysis.
The duration of the project work will be 6 months. Your main work location will be in the Zurich area.
