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…
Ab initio study of InxGa(1-x)N - performance of the alchemical mixing approximation
P. Scharoch, M. J. Winiarski, M. P. Polak
The alchemical mixing approximation which is the ab initio pseudopotential specific implementation of the virtual crystal approximation (VCA), offered in the ABINIT package, has be…
Anomalous band-gap bowing of AlN(1-x)Px alloy
M. J. Winiarski, M. Polak, P. Scharoch
Electronic structure of zinc blende AlN(1-x)$Px alloy has been calculated from first principles. Structural optimisation has been performed within the framework of LDA and the band…
First principles prediction of structural and electronic properties of TlxIn(1-x)N alloy
M. J. Winiarski, P. Scharoch, M. P. Polak
Structural and electronic properties of zinc blende TlxIn(1-x)N alloy have been evaluated from first principles. The band structures have been obtained within the density functiona…
