MOS-HEMT devices have erased a lot of interest in the state of art and specifically for compact and high power density applications. Thanks to the presence of a high bi-dimensional gas electron (2deg) at the AlGaN/GaN heterojunction and the very promising GaN thermal resistance and high mobility, these transistors are capable of supporting high currents […] >>

Microsystems sensors (MEMS) are the interface between the physical world and the digital world, and they are present today in most components and systems. A major challenge is the development of sensors that can be interrogated remotely, without electronic circuits or batteries, which will make it possible to envisage new applications as for example in […] >>

Today, memories are once again a priority for two reasons: data production is growing exponentially. Data storage and transfer consumes up to 90% of the energy in computing systems. Non-volatile memories, which retain information when not powered, are needed to limit energy consumption. Ferroelectric memories (FeRAM or FRAM) are one of the emerging non-volatile memory […] >>

A natural way to address the scalability of quantum devices is to design and realise arrays of individual quantum objects with nearest-neighbor interaction. In large-scale semiconductor quantum processors, a quantum bit is encoded in the spin of an isolated electron, trapped in an array of quantum dots (QDs) [1]. Over the years, we have studied […] >>

While topics around protection mechanisms or threat detection are currently well covered, post-attack repair is still not very present in the scientific literature. Objectives: The objective of this thesis is to identify solutions to restore critical functions or tasks of an embedded device after the detection of an unwanted event (due to a malicious attack […] >>
