Excess Noise in High-Current Diamond Diodes -- Physical Mechanisms and Implications for Reliability Assessment
Subhajit Ghosh, Harshad Surdi, Fariborz Kargar +5
We report results of an investigation of low-frequency excess noise in high-current diamond diodes. It was found that the electronic excess noise of the diamond diodes is dominated…
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…
Low-Frequency Electronic Noise Spectroscopy of Quasi-2D van der Waals Antiferromagnetic Semiconductors
Subhajit Ghosh, Fariborz Kargar, Amirmahdi Mohammadzadeh +2
We investigated low-frequency current fluctuations, i.e. noise, in the quasi-two-dimensional (2D) van der Waals antiferromagnetic semiconductor FePS3 with the electronic bandgap of…
Beatings of ratchet current magneto-oscillations in GaN-based grating gate structures: manifestation of spin-orbit band splitting
P. Sai, S. O. Potashin, M. Szola +8
We report on the study of the magnetic ratchet effect in AlGaN/GaN heterostructures superimposed with lateral superlattice formed by dual-grating gate structure. We demonstrate tha…
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…
