Researchers at INAC-PHELIQS-NPSC have developed new approaches for the detection of ultraviolet/infrared light using single GaN nanowires. Results have led to the demonstration of the first photodetector-in-a-wire based on intersubband transitions, i.e. electron transitions within quantum-confined ... More »

Three different services, SyMMES, MEM and PhELIQS from INAC institute, have been working together during the last year and a half within the framework of a collaborative intern project dealing with nitrogen doped-vertically oriented graphene nanosheets (N-VOGNs) for supercapacitor applications. The ... More »
Integration of charge sensors for the readout of semiconductor quantum bits (qubits) is required for a realistic realization of scalable quantum computer. Such charge-sensitive devices, however, involve a significant overhead in terms of gates and contact leads, posing an issue for scalability ... More »
In the context of the study of the interplay between magnetism and superconductivity, a phase transition has been evidenced as a function of magnetic field between two phases having identical magnetic symmetry. Since this effect cannot be magnetically driven, it implies a modification of the nature ... More »
The development of sensitive and compact readout tools of quantum states is a central issue in the run to industrial scalability of semiconductor quantum bits (qubits). We employ the gates of industrial silicon Field-Effect Transistors (used as qubits) as radio-frequency resonators integrated in ... More »
In a metal the energy levels of the electrons, which have to be all in different quantum states due to the Pauli exclusion principle, are filled up to the Fermi energy at zero temperature. The surface of constant energy in the reciprocal space separating occupied and unoccupied electronic states is ... More »
Moiré patterns are superlattice structures that appear when two crystals with a lattice mismatch or with a different orientation are superimposed. We have developed a universal classification of all possible periodic Moirés in order to determine their exact crystallographic ... More »
Leti, an institute of CEA Tech, along with Inac, a fundamental research division of CEA, and the University of Grenoble Alpes have achieved the first demonstration of a quantum-dot-based spin qubit using an industry-standard fabrication process. Published in the November 24 issue of Nature ... More »

We have studied the growth and optical properties of AlGaN nanowires, a potential candidate for future ultraviolet light sources. We have evidenced that such structures behave as a collection of quantum dots due to short-scale composition fluctuations. Nanowires made of nitride semiconductors ... More »

Nanowire transistors in the sub10 nm range are subject to process variability. A main cause is the surface roughness of the nanowire. A single dopant centered in the channel can also modify the room temperature electrical characteristics of the transistor.  Both the surface roughness and a ... More »
Atomically clean superconducting graphene has been grown on thin rhenium films. This breakthrough paves the way to new hybrid superconducting nanostructures.   Graphene is not an intrinsic superconductor but can become superconducting by proximity effect when it is intimately connected ... More »

  Whereas batteries provide energy over several hours, supercapacitors deliver energy peaks in seconds, and provide strong power. Balancing energy and power under constrained volumes is the key challenge for the growth of many industrial applications including the electric vehicle where ... More »
Scientists from the FOM foundation (Foundation for fundamental research on matter), the University of Twente and at the Institute for Nanoscience and Cryogenics in France have shown that light sources which usually emit light randomly can be coaxed to emit an ultrashort burst of light at a desired ...

Today microelectronics techniques allow the combination of optics and microfluidics on the same chip to handle colloidal objects. The SiNaPS laboratory, in collaboration with the Near Field Optics Group of University of Burgundy and the Microelectronics Technologies Laboratory in Grenoble (LTM), ... More »
