Project description - Motivation
Topological insulators
conduction is perfect, lossless, and unaffected by material imperfections.
Perfect candidates in
- Thermoelectrics
- Spintronics
- Quantum informatics
Where to find one?
Under mechanical strain graphene / BiTeX hybrids become topological insulators
SASPRO 2 Programme - Interview - Zoltán Tajkov
Project description - Objectives
1st key objective
Gradual increment using the explored physics
Mechanical strain is not necessary!
2nd key objective
Using the developed tools
Investigate more complicated materials
\( \alpha_1-\mathrm{Ta}\mathrm{Si}_2\mathrm{N}_4 \) and \( \alpha_1-\mathrm{Nb}\mathrm{Si}_2\mathrm{N}_4 \)
Ising superconductor and ferromagnetic semiconductor
- Topological superconductivity
- Majorana zero modes
Haven't been investigated before!
