Nonlinear modelling of AlN/GaN HEMT accounting for self-biasing effect during RF step stress: analysis and hard-SOA

N. Said, Damien Saugnon, Kathia Harrouche, F Medjdoub, Nathalie Labat, Nathalie Malbert, Jean-Guy Tartarin

In this study, we investigate the non-linear (NL) behavior of AlN/GaN HEMT under gain compression technologies when submitted to 10 GHz single-tone RF-step stress, crucial for millimeter-wave power application robustness. We evaluate AlN/GaN transistors, targeting high-power amplifiers with…

RF-Robustness enhancement in AlN/GaN HEMT through AlGaN Back-Barrier: nonlinear model analysis

N. Said, Damien Saugnon, Kathia Harrouche, Farid Medjdoub, Nathalie Labat, N. Malbert, Jean-Guy Tartarin

In this study, we evaluate the robustness and nonlinear (NL) responses of two variants of AlN/GaN HEMT technology under RF-step stress at 10 GHz. We develop an original NL behavioral modelling approach that includes the self-biasing effect within a unique expression. This method is applied to…

Towards the elimination of water in THz-TDS data

Noureddin Osseiran, Jeyan Bichon, Sophie Eliet, Romain Peretti

<div><p>One of the most problematic points in THz-TDS is the absorption induced by water lines. This absorption complicates and biases the fitting algorithms. We propose here an approach to eliminate water from TDS data. The 1parameter model can eventually be used to quantify water…

Can the THz-TDS detect trace gases?

Noureddin Osseiran, Jeyan Bichon, Sophie Eliet, Romain Peretti

The THz-TDS is a versatile technique and can be used to probe gas phase molecules. We are pushing the technique to its limit to try and detect trace gases at the sub-ppm levels. The experiments served as a reference for a quantitative approach that permits to extract the concentration of a probed…

Uncertainties estimation in THz-TDS experiments in transmittance, refractive index and spectroscopic parameters

Noureddin Osseiran, Jeyan Bichon, Théo Hannotte, Mouhamed Abdel-Kader, Martin Witt, Sophie Eliet, Romain Peretti

<div><p>Data processing is a key for the spreading of the THZ-TDS systems to more analytical fields. However, till today no standard methods exist to extract error bar from standard measurements in TDS besides the transmission. We propose here a methodology to reply to this challenge.…

Phonon polaritons impact atmosphere transparence in the TeraHertz range

Jeyan Bichon, Denis Petitprez, Hervé Herbin, Jean-Francois Lampin, Romain Peretti, Sophie Eliet

<div><p>Atmospheric aerosols impact the climate by modifying the radiative balance of the planet and the microphysical properties of clouds and by altering the biogeochemical balance of the atmosphere. Above all, some aerosols exhibit fascinating effects due to the phonon-polaritons…
