Excitonic luminescence of iodine-intercalated HfS
N. Zawadzka, T. Woźniak, M. Strawski +10
Photoluminescence from bulk HfS grown by the chemical vapor transport method is reported. A series of emission lines is apparent at low temperature in the energy range of 1.4 -…
Distinctive g-factor of moire-confined excitons in van der Waals heterostructures
Y. Galvão Gobato, C. Serati de Brito, Andrey Chaves +7
We investigated experimentally the valley Zeeman splitting of excitonic peaks in the photoluminescence (PL) spectra of high-quality hBN/WS2/MoSe2/hBN heterostructures at near-zero…
Temperature induced modulation of resonant Raman scattering in bilayer 2H-MoS
Mukul Bhatnagar, Tomasz Woźniak, Łucja Kipczak +7
The temperature evolution of the resonant Raman scattering from high-quality bilayer 2H-MoS encapsulated in hexagonal BN flakes is presented. The observed resonant Raman scat…
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…
