Investigation of Temperature, Well Width and Composition Effects on the Intersubband Absorption of InGaAs/GaAs Quantum Wells

Lynda Chenini, Abdelkader Aissat, Sofiane Ammi, Jean-Pierre Vilcot

Optical properties of the ternary InxGa1-xAs/GaAs alloys including strain, band gap energy, band offsets, and intersubband absorption coefficient in the conduction band (CB) are theoretically investigated. Effect of temperature, T, and Indium composition, In, of InGaAs on all these parameters is...

High Power AlN/GaN HEMTs with record power-added-efficiency >70% at 40 GHz

Kathia Harrouche, Riad Kabouche, Etienne Okada, F Medjdoub

We report on breakthrough power-added-efficiency (PAE) Q-band performances using a vertically scaled AlN/GaN HEMT technology. The comparison between a 3 nm and 4 nm barrier thickness shows both superior performance and robustness for the thinner barrier layer attributed to the reduced mechanical...

Elastic stubbed metamaterial plate with torsional resonances

Wei Wang​, Bernard Bonello, Bahram Djafari-Rouhani, Yan Pennec, Jinfeng Zhao

We report on a new mechanism involving the torsional resonance of stubs to achieve the negative effective shear modulus of an elastic metamaterial plate. Combined with a mechanism to create a negative mass density, we develop a general method to set up and enlarge a shear-horizontal-polarized...
