Coupling of advanced characterization techniques to study 2D material growth and integration

Two-dimensional (2D) materials are defined as crystalline solids consisting of a single layer of atoms, making their properties remarkable. Compared to their massive form, they can present outstanding semiconducting characteristics that can be exploited for many applications (CMOS, memories, photonics, photovoltaics, etc.). However, their integration into components via standard microelectronics processes remains a challenge and […] >>

Cryopenic control electronics dedicated to the control of a matrix of qubits

The recent improvements of quantum bits (qubit) based on electron spins pave the way towards their massive integration into the possible quantum processor of the future quantum computer. The individual biasing, manipulation and reading of particular qubits of the matrix is a key point that forges strong links between physicists and electronics engineers. More specifically, […] >>
