Optimization of metal oxides for the realization of electrode in adequacy with the photosensitive material in the near infrared

The thesis is part of a partnership between CEA-Léti and the Process Development Department of STMicroelectronics Crolles. The study will focus on the development of electrodes for image sensor applications. The next generations of image sensors will use chalcogenide, perovskite or ‘quantum dots’ photosensitive materials. These materials are inserted between electrodes to collect electrons and […] >>

Core-shell perovskite nanocrystals for photovoltaic applications

Halogenated perovskite materials have recently created a sensation in the field of photovoltaics and other optoelectronic applications because of the very high efficiencies obtained. Colloidal nanocrystals (NCs) of the perovskites have very recently attracted a lot of attention because of their unique optical properties, very high quantum yields and simple synthesis. The use of the […] >>

Superconductor / Semiconductor hybrid nanostructures based on Germanium for quantum information

Holes in germanium have the advantage to possess a strong spin-orbit coupling enabling fast electrical control of their spin. In addition, p-type germanium has the tendency to form low-Schottky-barrier contacts with several metals, including superconducting ones. This opens the opportunity to realize novel hybrid superconductor-semiconductor devices relying on the superconducting proximity effect in germanium. The […] >>

Short wave Infra Red diffuse reflectance spectroscopy for noninvasive molecular detection medical devices

Diabetes is a major public health and industrial issue, with the number of diabetics worldwide estimated at 415 million. Until recently, to control their blood glucose, patients had to prick their fingertips. To avoid this inconvenience, laboratories have recently been offering minimally invasive measurement systems that can be interrogated using a smartphone. This evolution, although […] >>

Modeling of silicon two qubit gates

“Quantum computers” may soon be able to solve problems beyond the reach of conventional computers. Such computers no longer manipulate electrons as particles, but as waves that maintain phase relationships and can interfere. The preparation, coherent manipulation and “reading” of quantum states is extremely challenging. One promising option for making “quantum bits” (qubits) is to […] >>
