Electronics

ELECTRONICS TEAM

PRESENTATION

Team leader : Laurence MECHIN

The “Electronics” team works on various research activities on advanced electronic components and high-sensitivity sensors, ranging from materials to devices and systems. Measured quantities include magnetic field, electric field, infrared and X-ray radiation, temperature and gas. The team’s expertise in measurement engineering can answer a variety of scientific, societal, industrial or cultural questions such as health, environment, non-destructive testing and device physics.

The team is organised in 3 axes:

Axis 1: Physics of semiconductor devices: noise, temperature, electronic defects

Axis 2: Functional oxides: from thin films to sensors

Axis 3: Complex measurement and detection systems: noise, sensors, instruments, applications

Key-words : Magnetic field, electric field, temperature, radiation, gas detection.

RESEARCH TOPICS

AXIS 1 : PHYSICS OF SEMICONDUCTOR COMPONENTS : NOISE, TEMPERATURE, ELECTRONIC DEFECTS

The performance of electronic components can be degraded by the presence of defects induced by technological manufacturing processes, by imposed electric fields and/or by ionizing radiation depending on the application. We have developed the necessary skills to characterize these defects by low-frequency noise measurements, pulsed electrical measurements and/or DLTS measurements. The study of low-frequency noise is also used as a non-destructive diagnostic tool to predict the quality and reliability of future electronic components. Components can be damaged by thermal effects. Original techniques are developed to estimate their heating, in particular by Raman spectroscopy.

The research activities are carried out in the framework of an international collaboration with imec (Leuven, Belgium) and also with local (CIMAP, CRISMAT, EAMEA), national (GPM Rouen, IEMN Lille) and industrial partners (III-V lab Marcoussis, Thales Land & Air Systems, Murata).

1) Study of electrical transport and identification of defects in semiconductor components

  • Low frequency noise
  • Influence of electrical stresses and neutron irradiation
  • Pulsed measurements
  • DLTS (Deep Level Transient Spectroscopy)

2) Thermal characterization of GaN transistors 

  • Raman spectroscopy
  • Electrical measurements

3) Study of passive components within the joint laboratory with Murata (IPDN)

  • Identification of defects by electrical characterization

AXIS 2: FUNCTIONAL OXIDES: FROM THIN FILMS TO SENSORS

The activities in this area are aimed at exploiting the particular physical properties of functional oxide thin films. The objectives are on the one hand to realize magnetic and radiation sensors and on the other hand the study of heterostructures and defects in these oxides in order to eventually design new sensors. Thin oxide layers are mainly deposited within the GREYC either by pulsed laser ablation or by sputtering.

The research activities are carried out within the framework of international collaborations with IMDEA (Madrid, Spain), SISSA (Trieste, Italy), IOM-CNR (Trieste, Italy), University of Cornell (USA) and also with local (CIMAP, CRISMAT, EAMEA), national (IEMN – Lille, Synchrotron Soleil – Saclay) and industrial partners (III-V lab Marcoussis, Thales Land & Air Systems, Murata).

AXIS 3 : COMPLEX SYSTEMS OF MEASUREMENT AND DETECTION: NOISE, SENSORS, INSTRUMENTS, APPLICATIONS

Axe 3 is interested in the study of complex measurement and detection systems with 3 themes: high sensitivity magnetic sensors, electric field sensors and smart detectors. The research carried out has in common a systemic approach to the problems. The analysis and implementation of sensors as well as applications require simultaneous consideration of the physical quantities of the system, noise, non-linearities, digital and / or analog signal processing and technological limitations of the components. The system approach makes it possible to link the entire sensitive element to the application.

The research activities are carried out within international collaborations with Virgina Tech andOffice Naval Research (USA), Darpa (USA), Polytechnique Montreal (Canada), NIST Boulder (USA), LIMMS/CNRS IIS (Tokyo, Japon) and also with local (LCS), nationaux (IEMN – Lille, Synchrotron Soleil – Saclay) and indusctrial partners (Corrodys, Chauvin Arnoux).
