Characterization and modeling of traps and RF frequency dispersion in AlGaN/AlN/GaN HEMTs

Hector Sanchez-Martin, Oscar Garcia-Perez, Ignacio Íñiguez-De-La-Torre, Susana Perez, Tomás González, Javier Mateos, Philippe Altuntas, N. Defrance, Marie Lesecq, Virginie Hoel, Yvon Cordier, Stephanie Rennesson

The performance of GaN transistors is still limited by physical and fabrication problems, mainly related to different kinds of traps. In this work, virgin transistors reveals strong low frequency dispersion both in the transconductance and output conductance, that we attribute to the presence of…

Theoretical investigation of the phonon-limited carrier mobility in (001) Si films

Jing Li, Evelyne Lampin, Christophe Delerue, Yann-Michel Niquet

We calculate the phonon-limited carrier mobility in (001) Si films with a fully atomistic framework based on a tight-binding (TB) model for the electronic structure, a valence-force-field model for the phonons, and the Boltzmann transport equation. This framework reproduces the electron and phonon…

Investigations on the mechanical properties of the elementary thin films composing a CuIn1−xGaxSe2 solar cell using the nano indentation technique.

Hocine Abib, Alain Iost, Alex Montagne, Khadidja Rahmoun, Boubakeur Ayachi, Jean-Pierre Vilcot

The aim of this work is to assess the mechanical properties of the different layers composing a CIGS based solar cell. Fabrication uses the magnetron sputtering deposition technique (except for the CdS layer which was deposited using chemical bath deposition process). We performed several…

Electronic structure investigation of Al0.7Ga0.3As/GaAs nanometric heterostructures by Kelvin force microscopy

Sylvain Pouch, Francois Triozon, Nicolas Chevalier, Thierry Melin, Yann Michel Niquet, Lukasz Borowik

Kelvin force microscopy provides a spatially resolved measurement of the surface potential, which is related to the energetic band structure of a material. The goal of this work is to investigate the surface potential on Al0.7Ga0.3As and GaAs heterostructures with a decreasing layer thickness up to…

Bulk acoustic wave transformer employing periodically polled array of piezoelectric rods

Victor Plessky, Ventsislav Yantchev, C. Granger, Anne-Christine Hladky

Multilayer bulk acoustic wave transformer employing a periodical array of piezoelectric rods with alternating polarization is experimentally demonstrated for the first time. Voltage transformation coefficient in excess of 6 was measured at a frequency of 150kHz, providing thus a solid experimental…

Improved performance of flexible CMOS technology using ultimate thinning and transfer bonding

Emmanuel Dubois, Justine Philippe, Matthieu Berthomé, J.F. Robillard, Christophe Gaquière, Francois Danneville, Daniel Gloria, Christine Raynaud

Based on a simple process referred to as ultimate thinning-and-transfer-bonding (UTTB), this paper shows that the high-frequency performance of advanced CMOS technologies can be combined with mechanical flexibility and transparency. The invariance upon thinning, transfer and flexure of both DC and…

Broadband dielectric characterization of aqueous saline solutions by an interferometer-based microwave microscope

S. Gu, Tianjun Lin, T. Lasri

The complex dielectric permittivity of aqueous saline solutions has been determined in the frequency range [2-18 GHz] with a home-made near-field microwave microscope. The instrument is built on a vector network analyzer, a matching network, and an evanescent microwave probe. The interferometer-…
