Nanofaceting as a stamp for periodic graphene charge carrier modulations [PDF]
Scientific Reports 6, Article number: 23663 (2016), 2016 The exceptional electronic properties of monoatomic thin graphene sheets triggered numerous original transport concepts, pushing quantum physics into the realm of device technology for electronics, optoelectronics and thermoelectrics. At the conceptual pivot point is the particular twodimensional massless Dirac fermion character of graphene charge ...

Electron-phonon coupling in copper intercalated Bi$_{2}$Se$_{3}$ [PDF]
arXiv, 2022 We report charge and heat transport studies in copper-intercalated topological insulator Bi$_2$Se$_3$ hybrid devices. Measured conductivity shows impact of quantum corrections, electron-electron and electron-phonon interactions. Our shot noise measurements reveal that heat flux displays a crossover between $T^2$ and $T^4$ with the increase of ...

Cu self-sputtering MD simulations for 0.1-5 keV ions at elevated temperatures [PDF]
Nuclear Inst. and Methods in Physics Research, B 415C (2018) pp.
31-40, 2017 Self-sputtering of copper under high electric fields is considered to contribute to plasma buildup during a vacuum breakdown event frequently observed near metal surfaces, even in ultra high vacuum condition in different electric devices. In this study, by means of molecular dynamics simulations, we analyze the effect of surface temperature and ...

Quantitative analysis of electronic transport through weakly-coupled metal/organic interfaces [PDF]
, 2008 Using single-crystal transistors, we have performed a systematic experimental study of electronic transport through oxidized copper/rubrene interfaces as a function of temperature and bias. We find that the measurements can be reproduced quantitatively in terms of the thermionic emission theory for Schottky diodes, if the effect of the bias-induced ...
