Work carried out within the CEA-Leti has shown that physical attacks can be a threat to the security mechanisms of SoCs (System-On-Chips). Indeed, fault injections by electromagnetic disturbance have already led to an elevation of privileges by authenticating with an illegitimate password, or more recently have made it possible to circumvent one of the highest […] >>

Master 2 internship topic Conception, fabrication and characterization of devices dedicated to identification and autthentication applications in THz domain   Subject : THz spectroscopy (1 THz = 10¹² Hz), born in the 80s, makes it possible to probe, thanks to the use offemtosecond lasers (1 fs = 10-¹5s), the electromagnetic properties of materials between 100 […] >>

Low frequency noise measurements under illumination for defect characterization in photovoltaic cells     Photovoltaic technologies are among the least carbon-intensive sources of energy and are therefore a fundamental research area in the current context of energy transition. Increasing the performance of these devices and their operating lifetime is one of the main challenges in […] >>

Straining the cristal lattice of a semiconductor is a very powerfull tool enabling controlling many properties such as its emission wavelength, its mobility…Making strain amplification microstructures is a rather recent technique allowing accumulating very significant amounts of strain in a micronic constriction, such as a microbridge (up to 4.9% for Ge [1]), which deeply drives […] >>

                            PhD.D. student  position at the  LMGP and IMEP-LAHC Laboratories in Grenoble Study of non-linear electromechanical effects on piezoelectric semiconducting nanowires Detailed subject : In recent years, there has been a growing interest in the international scientific community for the study of nanowires (NWs), whose one-dimensional (1D) character gives […] >>
