Crystal field tuned spin-flip luminescence in NiPS3
Léonard Schue, Nashra Pistawala, Hebatalla Elnaggar +8
Layered magnetic materials potentially hold the key to future applications based on optical control and manipulation of magnetism. NiPS3, a prototype member of this family, is anti…
Observation of resistive switching and diode effect in the conductivity of TiTe2 point contacts
O. E. Kvitnitskaya, L. Harnagea, O. D. Feia +3
We measured the I(V) and dV/dI(V) characteristics of TiTe2-based point contacts (PCs) from room to helium temperatures. Features indicating the emergence of a charge density wave (…
Ultrafast Dynamics of Coherent Phonon Modes in Excitonic Insulator TaNiSe
Vikas Arora, Sukanya Pal, Luminita Harnagea +2
The spontaneous condensation of excitons in the excitonic insulating phase has been reported in TaNiSe below 325 K. In this context, we present the temperature-dependent op…
Pressure Dependence of Ultrafast Carrier Dynamics in Excitonic Insulator TaNiSe
Vikas Arora, Victor S Muthu, Arijit Sinha +3
An excitonic insulator (EI) phase is a consequence of collective many-body effects where an optical band gap is formed by the condensation of electron-hole pairs or excitons. We re…
