Zintl-phase compounds garner attention as promising thermoelectric materials due to observations of phonon-glass electron-crystal (PGEC) behavior, in combination with tunability that allows optimization of properties and doping. However, this is very much dependent on the specific materials, and understanding the factors that lead to PGEC behavior in some Zintl compounds but not others is an ...
A trigonal semiconductor Si allotrope with 22 atoms in the primitive cell, named as Tri-${\\mathrm{Si}}_{22}$, is predicted by structural searching. The Tri-${\\mathrm{Si}}_{22}$ is the most stable phase among previous predicted structures with the same atomic number. Our state-of-the-art first-principles calculation for the band structure and optical properties shows that compared with the ...

Charge carrier mobility is at the core of semiconductor materials and devices optimization, and Hall measurement is one of the most important techniques for its characterization. The Hall factor, defined as the ratio between Hall and drift mobilities, is of particular importance. Here we study the effect of anisotropy by computing the drift and Hall mobility tensors of a technologically ...

The bulk photovoltaic effect (BPVE) has attracted increasing interest due to its potential to overcome the efficiency limit of traditional photovoltaics, and much effort has been devoted to understanding its underlying physics. However, previous work has shown that theoretical models of the shift current and the phonon-assisted ballistic current in real materials do not fully account for the ...
We present a theoretical study of photoabsorption in n-doped two-dimensional (2D) and quasi-2D semiconductors that takes into account the interaction of the photocreated exciton with Fermi-sea (FS) electrons through (i) Pauli blocking, (ii) Coulomb screening, and (iii) excitation of FS electron-hole pairs—that we here restrict to one.The system we tackle is thus made of one exciton plus zero ...
