Electron spin dynamics of two-dimensional layered materials
Bálint Náfrádi, Mohammad Choucair, László Forró
The growing library of two-dimensional layered materials is providing researchers with a wealth of opportunity to explore and tune physical phenomena at the nanoscale. Here, we rev…
Doped carbon nanotubes as a model system of biased graphene
P. Szirmai, B. G. Márkus, B. Dóra +8
Albeit difficult to access experimentally, the density of states (DOS) is a key parameter in solid state systems which governs several important phenomena including transport, magn…
Anisotropic Elliott-Yafet Theory and Application to KC Potassium Intercalated Graphite
Bence G. Márkus, Lénárd Szolnoki, Dávid Iván +5
We report Electron Spin Resonance (ESR) measurements on stage-I potassium intercalated graphite (KC). Angular dependent measurements show that the spin-lattice relaxation time…
Photodiode Response in a CHNHPbI/CHNHSnI Heterojunction
M. Spina, L. Mihály, K. Holczer +4
Since the discovery of its photovoltaic properties organometallic salt CHNHPbI became the subject of vivid interest. The material exhibits high light conversion efficie…
Metallicity and conductivity crossover in white light illuminated CHNHPbI perovskite
A. Pisoni, J. Jacimovic, B. Náfrádi +7
The intrinsic d.c. electrical resistivity () - measurable on single crystals only - is often the quantity first revealing the properties of a given material. In the case of CH$_…
Tuning of the Thermoelectric Figure of Merit of CHNHMI (M=Pb,Sn) Photovoltaic Perovskites
Xavier Mettan, Riccardo Pisoni, Péter Matus +7
The hybrid halide perovskites, the very performant compounds in photovoltaic applications, possess large Seebeck coefficient and low thermal conductivity making them potentially in…
