The purpose of this project is to calculate the electronic structure of III-V semiconductor (InAs/GaSb) core-shell and core-shell-shell nanowires. The calculations will primarily use k.p theory combined with the envelope function approximation. Both applied electric and magnetic fields will be taken into account, which, in combination with the heterostructured nanowires leads to significant computational costs as most symmetries are broken.
We are now starting a second phase of this research program, in which we investigate the possible topological properties of core-shell and core-shell-shell nanowires. This will involve the same type of k.p calculations we used previously, but also tight-binding methods will be used.
The project is a continuation of SNIC 2016/4-64, but the main investigator is changed from Martin Leijnse to Florinda Viñas Boström.
