Internal structure of ferroelectric nanocrystals: coupling between local piezoresistance microscopy and optical measurements
Stage M2CEA Saclay, Site de l’Orme des merisiers (91) Essonne, FranceFebruary 1 20244 monthDomain, Specialties : Condensed matter physics Keywords: Nanosciences, nanotechnologies, photonics, local probe microscopy Research Unit : SPEC / LEPO This internship aims at correlating local probe measurements (AFM electrical modes) to optical measurements (frequency conversion, in particular 2nd harmonic generation – SHG) in order to reveal the structure of piezoelectric nanocrystals towards a better understanding…

Study of electronic processes in nitride LEDs by electro-emission microscopy
November 21 20246 monthDomain, Specialties : Condensed matter physics Keywords: Energy efficient devices, semiconductors, microscopy Research Unit : SPEC / LEPO Although nitride LEDs are extremely efficient at low indium content (for blue emission) and low current densities, they suffer from drastic drops in efficiency when going out of theses regimes, partly due to an increase of Auger-Meitner…
