Effect of current on terahertz plasmons in AlGaN/GaN heterostructures
M. Dub, P. Sai, Y. Ivonyak +3
Terahertz transmittance spectra of plasmonic crystals based on two-dimensional electron gas in AlGaN/GaN heterostructures were studied in grating-gate and gateless plasmonic crysta…
The dissociation of (a+c) misfit dislocations at the InGaN/GaN interface
J. Smalc-Koziorowska, J. Moneta, G. Muziol +5
(a+c) dislocations in hexagonal materials are typically observed to be dissociated into partial dislocations. Edge (a+c) dislocations are introduced into (0001) nitride semiconduct…
Electrically pumped blue laser diodes with nanoporous bottom cladding
Marta Sawicka, Grzegorz Muziol, Natalia Fiuczek +8
We demonstrate electrically pumped III-nitride edge-emitting laser diodes (LDs) with nanoporous bottom cladding. The LD structure was grown by plasma-assisted molecular beam epitax…
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…
Thermal Annealing Effect on Electrical and Structural Properties of Tungsten Carbide Schottky Contacts on AlGaN/GaN heterostructures
Giuseppe Greco, Salvatore Di Franco, Corrado Bongiorno +4
Tungsten carbide (WC) contacts have been investigated as a novel gold-free Schottky metallization for AlGaN/GaN heterostructures. The evolution of the electrical and structural/com…
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…
