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…

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…
