Straightforward bias- and frequency-dependent small-signal model extraction for single-layer graphene FETs

Nikolaos Mavredakis, Anibal Pacheco-Sanchez, Wei Wei, Emiliano Pallecchi, Henri Happy, David Jiménez

We propose an explicit small-signal graphene field-effect transistor (GFET) parameter extraction procedure based on a charge-based quasi-static model. The dependence of the small-signal parameters on both gate voltage and frequency is precisely validated by high-frequency (up to 18 GHz) on-wafer...

Ternary SRAM circuit designs with CNTFETs

Doaa Abdelrahman, Mohammed Fouda, Ihsen Alouani, Lobna Said, Ahmed Radwan

SummaryStatic random-access memory (SRAM) is a cornerstone in modern microprocessors architecture, as it has high power consumption, large area, and high complexity. Also, the stability of the data in the SRAM against the noise and the performance under the radian exposure are main concern issues....

Flat band induced topological photonic Tamm states in stubbed structures: Theory and experiment

Soufyane Khattou, Yamina Rezzouk, Mohamed El Ghafiani, Madiha Amrani, Mohammed Elaouni, El Houssaine El Boudouti, Abdelkrim Talbi, Abdellatif Akjouj, Bahram Djafari-Rouhani

We provide theoretical and experimental evidence for the existence of topological Tamm states at the interface between two stubbed photonic crystals (PCs) as a function of the period and length of the stubs. Several works have addressed these states in the well-known Su-Schrieffer-Heeger model, a...

Thermal effects on fracture and the brittle-to-ductile transition

Andrea Cannizzo, Stefano Giordano

The fracture behavior of brittle and ductile materials can be strongly influenced by thermal fluctuations, especially in micro-and nano-devices as well as in rubberlike and biological materials. However, temperature effects, in particular on the brittle-to-ductile transition, still require a deeper...

Thermal and statistical analysis of various AlN/GaN HEMT geometries for millimeter Wave applications

Nasri Said, Kathia Harrouche, F Medjdoub, N. Labat, Jean-Guy Tartarin, N. Malbert

Downscaling HEMT devices is nowadays substantial to allow their operation in the millimeter wave frequency domain. In this work, the electrical parameters of three different AlN/GaN structures featuring various GaN channel thicknesses were compared. After a DC electrical stabilization procedure, 96...
