Název v původním jazyce

Magneto-optical studies of two-dimensional materials using THz Electron Spin Resonance

Popis výsledku v původním jazyce

Transition metal dichalcogenides (TMDs) figure among the most promising 2D materials and candidates for the next generation of 2D electronics, flexible electronics, spintronics [1](eg, MoS2 [2]). Unlike their three-dimensional counterparts, which are semiconductors with an indirect band gap, single layered TMDs usually have a direct band gap [3]. Electron spin resonance (ESR) can detect resonant absorption of electromagnetic radiation corresponding to transitions between levels of electron spin states, caused by internal effects and/or an applied external magnetic field. The strength of such interactions in materials can range from tens of MHz to tens of THz. That is why the extension of the ESR frequency range to higher values is one of the main challenges of modern ESR spectroscopy nowadays. We propose to apply THz-ESR to investigate solid-state samples such as TMDs in order to reveal their magneto-optical properties. The emphasis will be put on bulk single-crystal TMDs as well as on thin films of TMDs all the way down to a monolayer.
