Stress-Tuned Optical Transitions in Layered 1T-MX2 (M= Hf, Zr, Sn; X= S, Se) Crystals
Miłosz Rybak, Tomasz Woźniak, Magdalena Birowska +5
Optical measurements under externally applied stresses allow us to study the materials' electronic structure by comparing the pressure evolution of optical peaks obtained from expe…
Strong substrate strain effects in multilayered WS2 revealed by high-pressure optical measurements
Robert Oliva, Tomasz Woźniak, Paulo E. Faria Junior +5
The optical properties of two-dimensional materials can be effectively tuned by strain induced from a deformable substrate. In the present work we combine first-principles calculat…
The effect of isovalent doping on the electronic band structure of group IV semiconductors
Maciej P Polak, Paweł Scharoch, Robert Kudrawiec
The band gap engineering of group IV semiconductors has not been well explored theoretically and experimentally, except for SiGe. Recently, GeSn has attracted much attention due to…
Invariant expansion of the 30-band k.p model and its parameters for III-V compounds
Krzysztof Gawarecki, Paweł Scharoch, Michał Wiśniewski +4
In this work we derive a ready-to-use symmetry invariant expansion of the full-zone 30-band k.p Hamiltonian for the Td point group. In order to find respective parameters, the band…
