Raman scattering fingerprints of the charge density wave state in one-dimensional NbTe
Natalia Zawadzka, Cem Sevik, Zahir Muhammad +4
Charge-density waves (CDWs) are ordered quantum states of conduction electrons accompanied by periodic lattice distortions. Raman scattering (RS) spectroscopy is therefore well sui…
Electrically modulated light-emitting diodes driven by resonant and antiresonant tunneling between CrGeTe electrodes
Natalia Zawadzka, Kristina Vaklinova, Tomasz Woźniak +7
Exploring the electron tunneling mechanisms in diverse materials systems constitutes a versatile strategy for tailoring the properties of optoelectronic devices. In this domain, bi…
Fast Interlayer Energy Transfer from the Lower Bandgap MoS2 to the Higher Bandgap WS2
Gayatri, Mehdi Arfaoui, Debashish Das +9
Energy transfer (ET) is a dipole-dipole interaction, mediated by the virtual photon. Traditionally, ET happens from the higher (donor) to lower bandgap (acceptor) material. However…
Extremely high excitonic -factors in 2D crystals by alloy-induced admixing of band states
Katarzyna Olkowska-Pucko, Tomasz Woźniak, Elena Blundo +24
Monolayers (MLs) of semiconducting transition metal dichalcogenides (\mbox{S-TMDs}) emit light very efficiently and display rich spin-valley physics, with gyromagnetic (-) facto…
Size dependence of biexciton binding energy in strained ZnTe/(Zn,Mg)Te nanowire quantum dots
P. Baranowski, M. Zielinski, M. Szymura +6
Nanowire quantum dots, i.e., heterostructures consisting of an axial insertion of low bandgap semiconductor within large band gap semiconductor nanowire, attract interest due to th…
Twisted MoSe2 Homobilayer Behaving as a Heterobilayer
Arka Karmakar, Abdullah Al-Mahboob, Natalia Zawadzka +11
Heterostructures (HSs) formed by the transition-metal dichalcogenides (TMDCs) materials have shown great promise in next-generation optoelectronic and photonic applications. An art…
Pressure-induced optical anisotropy of HfS
Igor Antoniazzi, Tomasz Woźniak, Amit Pawbake +8
The effect of pressure on Raman scattering (RS) in the bulk HfS is investigated under hydrostatic and non-hydrostatic conditions. The RS lineshape does not change significantly…
Optical properties of orthorhombic germanium sulfide: Unveiling the Anisotropic Nature of Wannier Exciton
Mehdi Arfaoui, Natalia Zawadzka, Sabrine Ayari +7
To fully explore exciton-based applications and improve their performance, it is essential to understand the exciton behavior in anisotropic materials. Here, we investigate the opt…
The effect of temperature and excitation energy on Raman scattering in bulk HfS
Igor Antoniazzi, Natalia Zawadzka, Magdalena Grzeszczyk +6
Raman scattering (RS) in bulk hafnium disulfide (HfS) is investigated as a function of temperature (5 K 350 K) with polarization resolution and excitation of several laser…
Analogy and dissimilarity of excitons in monolayer and bilayer of MoSe
Łucja Kipczak, Artur O. Slobodeniuk, Tomasz Woźniak +8
Excitons in thin layers of semiconducting transition metal dichalcogenides are highly subject to the strongly modified Coulomb electron-hole interaction in these materials. Therefo…
Excitons and trions in WSSe monolayers
Katarzyna Olkowska-Pucko, Elena Blundo, Natalia Zawadzka +15
The possibility of almost linear tuning of the band gap and of the electrical and optical properties in monolayers (MLs) of semiconducting transition metal dichalcogenide (S-TMD) a…
Excitonic luminescence of iodine-intercalated HfS
