Temperature and Electron Concentration Dependences of 1/f Noise in HgCdTe -- Evidence for a Mobility Fluctuations Mechanism
Adil Rehman, Volodymyr Petriakov, Ivan Yahniuk +9
HgCdTe is a unique material with the band-gap tunable by the temperature, pressure, and cadmium content in a wide range, from 1.6 eV to inverted band-gap of -0.3 eV. Th…
HgTe quantum wells for QHE metrology under soft cryomagnetic conditions: permanent magnets and liquid temperatures
I. Yahniuk, A. Kazakov, B. Jouault +11
HgTe quantum wells with a thickness of 7 nm may have a graphene-like band structure and have been recently proposed to be potential candidates for quantum Hall effect (QHE)…
Nature of the 1/f Noise in Graphene, Direct Evidence for the Mobility Fluctuations Mechanism
Adil Rehman, Juan Antonio Delgado Notario, Juan Salvador Sanchez +6
The nature of the low-frequency current fluctuations, i.e. carrier number vs. mobility, defines the strategies for noise reduction in electronic devices. While the 1/f noise in met…
Efficient Absorption of Terahertz Radiation in Graphene Polymer Composites
Zahra Barani, Kamil Stelmaszczyk, Fariborz Kargar +4
We demonstrate that polymer composites with a low loading of graphene, below 1.2 wt. %, are efficient as electromagnetic absorbers in the THz frequency range. The epoxy-based graph…
Electrically-Insulating Flexible Films with Quasi-One-Dimensional van-der-Waals Fillers as Efficient Electromagnetic Shields
Zahra Barani, Fariborz Kargar, Yassamin Ghafouri +8
We report polymer composite films containing fillers comprised of quasi-one-dimensional (1D) van der Waals materials, specifically transition metal trichalcogenides containing 1D s…
Graphene Composites as Efficient Electromagnetic Absorbers in the Extremely High Frequency Band
Zahra Barani, Fariborz Kargar, Konrad Godziszewski +6
We report on the synthesis of the epoxy-based composites with graphene fillers and testing their electromagnetic shielding efficiency by the quasi-optic free-space method in the ex…
Perspectives of HgTe Topological Insulators for Quantum Hall Metrology
Ivan Yahniuk, Sergey S. Krishtopenko, Grzegorz Grabecki +16
We report the studies of high-quality HgTe/(Cd,Hg)Te quantum wells (QWs) with a width close to the critical one , corresponding to the topological phase transition and graphen…
