Pressure-Driven Phase Transition in Two-Dimensional Perovskite MHy2PbBr4
Mirosław Mączka,Szymon Sobczak,Paulina Ratajczyk,Fabio Furtado Leite,Waldeci Paraguassu,F. Dybala,Artur P. Herman,Robert Kudrawiec,Andrzej Katrusiak +8 more
TL;DR: In this paper , a 2D hybrid perovskite with a very small spacer cation (methylhydrazinium, MHy+) was studied for high pressure single-crystal X-ray diffraction, Raman spectroscopy, and optical studies.

Nesting-like band gap in bismuth sulfide Bi2S3
TL;DR: In this article, the optoelectronic properties of the van der Waals material Bi2S3 have been investigated using various experimental techniques under different temperature and hydrostatic pressure conditions, and the fundamental absorption edge and photoreflectance transition value has been found to be ∼ 1.30 eV at room temperature, which is the optimum value for a single-junction solar cell.

Pressure and temperature tuning of laser diodes
TL;DR: In this paper, a combination of pressure/temperature tuning with tuning by external grating was proposed to combine the merits of both methods: wide spectral range, narrow linewidth, stable emission wavelength.
Pressure dependence of direct optical transitions in ReS2 and ReSe2
R. Oliva,Magdalena Laurien,F. Dybala,J. Kopaczek,Y. Quin,Sefaattin Tongay,Oleg Rubel,Robert Kudrawiec +7 more
TL;DR: In this article, an experimental and theoretical study of the electronic band structure of ReS2 and ReSe2 at high hydrostatic pressures was performed by photoreflectance spectroscopy and analyzed in terms of ab initio calculations within the density functional theory.
Hidden spin-polarized bands in semiconducting 2H-MoTe2
TL;DR: In this paper, experimental and theoretical studies of the electronic band structure of 2H-MoTe2 at high hydrostatic pressures are presented. But the experimental results are limited to the case where the band structure is known.
