2020年10月30日 · Obtained results indicate the key role of spin–orbit interaction in the inversion of Bi and Se p orbitals in the bulk electronic structure. They reveal that the Dirac cone in the surface band structure is built up by pz states associated mainly with …

2016年10月15日 · In this chapter I will present the fundamentals of the studied systems. I will begin by identifying the crystal structure of each system as well as their point and space group symmetries. From there I will move on to a review of measurements of the bulk vibrational structure using Raman, IR, and inelastic neutron scattering spectroscopies.

Using ab initio molecular dynamics simulations, we have studied realistic amorphous Bi_2Se_3 phases generated by different processes of melting, quenching, and annealing.

2014年2月28日 · Here we report a new phenomenon of the spin texture locking with the orbital texture in a topological insulator Bi 2 Se 3. We observe light-polarization-dependent spin texture of both the upper...

For this purpose, a layer-by-layer thinning method by thermal sublimation for manufacturing large-scale mixed few-layer GeSe with direct bandgaps is proposed, and an optimized sublimation...

2021年11月19日 · Herein, we present a comprehensive summary on the recent advances of 2D Bi 2 Se 3 materials. The structure and inherent properties of Bi 2 Se 3 are firstly described and its preparation approaches (i.e., solution synthesis and van …

2020年11月6日 · In this paper, we study effects of substitution by the transition metal ions (Mn, Fe, Co and Ni) into Bi 2 Se 3 on its electric properties. Using the ab inito supercell technique, we investigate the density of states and the projected band structure. Under such substitution the shift of the Fermi level is observed.

2016年8月3日 · Using first-principles calculations, we investigate the dispersion and symmetry of the complex bands of Bi 2 Se 3 family of three-dimensional topological insulators. We compare the CBS of a band insulator and a topological insulator and follow the CBS evolution in both when the spin–orbit interaction is turned on.

2021年12月25日 · A quantum ballistic transport simulations was performed using a tight-binding Hamiltonian in the atomic orbital basis to assess the feasibility of Bi2 Se 3 for an alternative channel material in MOSFETs [170].
