This thesis deals with the monolithic integration of long wavelength (1.3-1.55 µm) p-i-n photodiodes with HEMT field effect transistors for the realization of wide bandwidth OEIC receivers for lightwave communication systems. Part of this work was carried ...
In this letter, we present normally-off GaN-on-Si MOSFETs based on the combination of tri-gate with a short barrier recess to yield a large positive threshold voltage (VTH), while maintaining a low specific on resistance (RON,SP) and high current density ( ...
InAlAs/InGaAs pseudomorphic HEMTs suffer from two drawbacks which can impede their future developments: a mechanical instability of their strained layers and a low breakdown voltage. In this work we study pseudomorphic structures where the channel and the ...
Organic thin-film transistors (TFTs) have undergone tremendous progress in the past few years. Their great potential in terms of mechanical flexibility, light weight, low-cost and large-area fabrication makes them promising candidates for novel electronic ...
We present AlGaN/GaN nanostructured Schottky barrier diodes (SBDs) on silicon substrate with high breakdown voltage (V-BR) and low reverse leakage current (I-R), based on a hybrid of tri-anode and tri-gate architectures. The fabricated SBDs presented a sma ...
In this paper we present a novel device, the Germanium Electron-Hole Bilayer Tunnel FET (Ge EHBTFET), which exploits carrier tunneling through a bias-induced electron-hole bilayer. The proposed architecture provides a quasi-ideal alignment between the tunn ...
A 4H-SiC pressure sensor with piezoresistive transducers, for harsh environment applications, e.g., high temperature (~650°C) and/or in corrosive chemicals is presented. The sensing membrane, 1 mm in diameter and 50 µm in thickness, was formed by milling ( ...

GaN based electronic devices have progressed rapidly over the past decades and are nowadays starting to replace Si and classical III-V semiconductors in power electronics systems and high power RF amplifiers. AlGaN/GaN heterostructures have been, until rec ...
In this letter, we introduce and demonstrate the concept of slanted tri-gates to enhance the breakdown voltage (V-BR) in lateral GaN power devices. Conventionally, field plates (FPs) are used to enhance the V-BR by distributing more homogeneously the elect ...
