The influence of proximity induced ferromagnetism, superconductivity and Fermi-velocity on evolution of Berry phase in BiSe topological insulator
Parijat Sengupta
BiSe is a well known 3D-topological insulators(TI) with a non-trivial Berry phase of attributed to the topology of the band structure. The Berry p…
Numerical guidelines for setting up a general purpose k.p simulator with applications to quantum dot heterostructures and topological insulators
Parijat Sengupta, Hoon Ryu, Sunhee Lee +2
The k.p perturbation method for determination of electronic structure first pioneered by Kohn and Luttinger continues to provide valuable insight to several band structure features…
Proximity induced ferromagnetism, superconductivity, and finite-size effects on the surface and edge states of topological insulator nanostructures
Parijat Sengupta, Tillmann Kubis, Yaohua Tan +1
BiTe and BiSe are well known 3D-topological insulators. Films made of these materials exhibit metal-like surface states with a Dirac dispersion and possess…
Atomistic and continuum modeling of a zincblende quantum dot heterostructure
Parijat Sengupta, Sunhee Lee, Sebastian Steiger +2
A multiscale approach was adopted for the calculation of confined states in self-assembled semiconductor quantum dots (QDs). While results close to experimental data have been obta…
