After his diploma in physics in 1993 he worked for more than 20 years at Omicron NanoTechnology (now Scienta Omicron) in test, service, engineering and product management. Bernd is specialized in Scanning Probe Microscopy, Thin Film Systems and Surface Science Instrumentation.
He returned as PhD student in 2015 to the Saarland University in Saarbrücken (Germany) and started research on the elasticity of freestading graphene membrane (B. Uder et al. Nanoscale 2018, 10, 2148 “Low-force spectroscopy on graphene membranes by scanning tunneling microscopy”) and obtained his PhD in Physics in 2018.
Joana Ferreira
Joana Ferreira is a PhD candidate in Physics and Materials Science at the university of Luxembourg, in the Scanning Probe Microscopy Laboratory, under the supervision of Alex Redinger. Her research is based on the epitaxial growth of tin perovskites and their characterization.
She received the BSc and the MSc in Physics from the university of Luxembourg. Her Master thesis was carried out in the LPM group at the University of Luxembourg and consisted in the study of polymer crystallization using fast differential scanning calorimetry.
Himanshu Phirke is a PhD candidate in Physics at the University of Luxembourg in the Scanning Probe Microscopy Laboratory of Alex Redinger. His research focuses on the correlation of optical and electronic properties of halide perovskite and CIGS using PL and KPFM.
He received his BSc in Physics from University of Pune, India and his MSc in Physics from California State University Northridge, USA. His Master thesis was based on STM and the study of the work function change of Graphene on copper and Nitrogen-doped graphene on copper.

In 2012 he joined as a trainee at Tunneling and Atomic Force Microscopy Group - MTA/LNNano (currently laboratory for Surface Science - LCS/LNNano). From 2013 to 2018, he worked as a specialist technician of the same group. He has a vast experience in scanning probe microscopy based technique, such as STM, AFM, EFM, KPFM, MFM, SCM, NanoIR, SNOM, LFM, Nanolithography, etc.
Christian Kameni
Boumenou
Christian KAMENI BOUMENOU is a PhD candidate in the scanning probe microscopy (SPM) Lab of the university of Luxembourg. His research topic is mainly based on the nanoscale investigation of the surfaces, interfaces and grain boundaries and the electronic properties of polycrystalline Cu(In, Ga)Se2 thin film solar cells absorber layers, by using different surface sensitive characterization techniques such as STM, STS and KPFM. Additional measurements like XPS and UPS are also used.
He received his BSc in physics and MSc degree by coursework in materials science from the university of Yaounde 1, in Cameroon. He then went to Nelson Mandela University (NMU) in South Africa where he obtained a second MSc degree by research where his Master thesis was on cross-sectional surface potential imaging of n-type/p-type GaAs grown on semi-insulating GaAs using both amplitude and frequency modulation KPFM. His research works were carried out in the semiconductor materials and nanostructures Lab of Professor Reinhardt Botha.
Jonathan Rommelfangen is a Phd candidate in Physics and Materials Science at the University of Luxembourg. His research is focused in scanning probe microscopy based techniques based on the 2D material MoS2.
He received his BSc and MSc in Physics from the University of Luxembourg. His Master thesis carried ou in the SPM group was on the growth and characterizations of MoS2.
