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…
