Mono-layer, so-called two-dimensional (2D), materials with a tunnelable band gap, e.g. phosphorene, are becoming very promising for potentially device applications. Tunnel field-effect transistors (TFETs) are expected to give rise to a new generation of low-power consumption logic switches. To date, TFETs are being investigated and built from conventional semiconductors, less often from 2D materials. Your task is from first-principles to characterize/study 2D-material-based TFETs, e.g. hetero-bilayer TFETs. The 2D Materials can be defined starting the project according to the student interest.

Short Description

The goal of the project is to develop methods and try new materials when modeling 2D heterostructures for quantum transport simulations, specifically focusing on how we can efficiently use DFT tools to simulate van derWaals heterostructures and semiconductor-oxide interfaces. By the end you should be able to model a material interface and characterize it using quantum transport. Single-layer 2-D materials and van der Waals heterostructures made of transition metal dichalcogenides such asMoS2 has proven to be viable candidates for future generations of transistor devices, enabling device scaling to new extremes. However, the huge number of possible material combinations to explore makes computational modeling necessary. We therefore aim to develop new efficient methods to explore these materials.

The work will manly consist of understanding and performing DFT calculations using tools such as Quantum Espresso and VASP, but also writing code to prepare and process simulations. The generated material systems will be analyzed using quantum transport tools. To do all this, you have access to our group's impressive computational cluster. We are seeking a candidate with a strong interest in device physics and physical simulations. Basic programming skills, for example in Python or MATLAB, are required together with a fundamental knowledge of quantum and semiconductor physics. Experience with DFT simulations and quantum transport are advantageous
