Electrical activity at the AlN/Si Interface: identifying the main origin of propagation losses in GaN-on-Si devices at microwave frequencies, Activité électrique de l'interface AlN/Si: identification de l'origine principale des pertes de propagation en hyperfréquences dans les composants GaN sur Silicium

Micka Bah, Damien Valente, Marie Lesecq, N. Defrance, Maxime Garcia Barros, Jean-Claude de Jaeger, Eric Frayssinet, Rémi Comyn, Thi Huong Ngo, Daniel Alquier, Yvon Cordier

AlN nucleation layers are the basement of GaN-on-Si structures grown for light-emitting diodes, high frequency telecommunication and power switching systems. In this context, our work aims to understand the origin of propagation losses in GaN-on-Si High Electron Mobility Transistors at microwaves…

Thermal resistance of an interfacial molecular layer by first-principles molecular dynamics

Thuy-Quynh Duong, Carlo Massobrio, Guido Ori, Mauro Boero, Évelyne Martin

The approach-to-equilibrium molecular dynamics (AEMD) methodology is applied in combination with first-principles molecular dynamics (FPMD) to investigate the thermal transfer between two silicon blocks connected by a molecular layer. Our configuration consists of alkanes molecules strongly coupled…

Low-temperature-grown gallium arsenide photoconductors with subpicosecond carrier lifetime and photoresponse reaching 25 mA/W under 1550 nm CW excitation

Charbel Tannoury, Maximilien Billet, Christophe Coinon, Jean-Francois Lampin, Emilien Peytavit

The authors show in this Letter that photoconductors based on GaAs grown at low temperatures can exhibit photoresponses as high as 25 mA/W under continuous-wave 1550-nm-wavelength illumination. It is achieved by using an optical Fabry-Pérot cavity in order to improve the external quantum efficiency…

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…
