Maria Tchernycheva

Maria Tchernycheva is a Directrice de recherche CNRS at the Center of Nanosciences and Nanotechnologies (C2N) in Palaiseau, Université Paris-Saclay. She holds a PhD in physics from Université Paris Sud (2005) and has over 120 peer-reviewed publications. Her work focuses on semiconductor nanowire fabrication and optoelectronic device development.

• PhD: Université Paris Sud (2005)
• Education: Ecole Polytechnique (X98)

Her research explores flexible optoelectronics using III-nitride nanowires for LEDs, solar cells, and piezosensors. Key innovations include polymer-embedded nanowire membranes and silver nanowire electrodes enabling bendable devices. She investigates electron beam induced current (EBIC) microscopy and cathodoluminescence (CL) for nanowire property analysis.

Project highlights include the ERC-funded NanoHarvest initiative, which achieved bi-color flexible LEDs with InGaN/GaN heterostructures. Her team demonstrated stretchable transparent LEDs and high-efficiency piezogenerators with GaN nanowire arrays. She also pioneered selective area epitaxy on graphene nanodots for van der Waals integration.

• Madeleine Lecoq Award (2006)
• ERC Starting Grant (2014)

Her NanoHarvest project team included 4 PhD candidates and 3 postdocs, with collaborations across institutions like Université Paris-Sud and CNRS. She has extensively published on surface charge effects and nanowire heterostructure optimization, with recent works spanning quantum-dot lasers and advanced passivation techniques.
