Within the OPTOCARSEMO project – “New approaches in optical characterization of mixed semiconductor oxides based on nanoscale correlative methods”, the team members of the Department of Microelectronics and Biomedical Engineering (DMIB), Faculty of Computers, Informatics and Microelectronics (FCIM) of the Technical University of Moldova carried out a research internship at the National University of Science and Technology POLITEHNICA Bucharest, within the Center for Microscopy – Microanalysis and Information Processing. This research internship is part of the continuous efforts to develop experimental research and consolidate international academic collaborations, with the main objective of achieving advanced characterizations of materials based on semiconductor oxides through modern microscopy and optical nanoscopy techniques.
During the research internship, team members participated in coordination and planning activities, in order to synchronize the implementation stages of the project, as well as in experimental investigations carried out using advanced techniques, such as Raman spectroscopy, bright field optical microscopy, confocal microscopy (CLSM – Confocal Laser Scanning Microscopy), atomic force microscopy (AFM – Atomic Force Microscopy) and absorption/transmission spectroscopy. At the same time, team members became familiar with the operation, configuration and calibration of high-precision equipment, as well as with modern methods of analysis and interpretation of experimental data, measurements being carried out under different conditions to evaluate the morphological, electronic and optical properties of the investigated semiconductor oxide-based materials.
In addition to the experimental activities, the team participated in Poli ChemistryFEST (5th edition, March 19–20, 2026), a major event organized by the Faculty of Chemical Engineering and Biotechnologies, focused on promoting the latest trends in nanoscience and bioengineering. The team members were also present at the scientific seminar “Spin Wave-based Computing”, held by Sorin D. Cotofana, during which fundamental concepts regarding the use of spin waves in computing systems were presented and mentioned, highlighting their potential as an innovative direction in microelectronics for the development of future computing architectures.
Participation of the team members of the Department of Microelectronics and Biomedical Engineering — Serghei RAILEAN, associate professor, PhD, Nicolai ABABII, associate professor, PhD, Maxim CHIRIAC, asst. professor, PhD, and Dinu LITRA, asst. professor, PhD — in these activities, emphasizes the continuous commitment to promoting frontier research and strengthening international collaborations in the field of nanoscale optical characterization of materials based on semiconductor oxides.
The activities carried out have significantly contributed to the development of the practical skills of the team members and have facilitated a valuable exchange of experience between researchers. In this context, concrete opportunities for collaboration were identified for the future stages of the project, including for the joint development and publication of scientific results.
The research internship allowed the achievement of the proposed objectives and the obtaining of relevant experimental results, which will contribute to future publications within the project. At the same time, this research internship has strengthened the collaborative relations between the Center for Nanomaterials and Nanosensors (DMIB, UTM) and the Center for Microscopy – Microanalysis and Information Processing (UPB), creating solid premises for the development of joint scientific initiatives and increasing the international visibility of the research carried out within the DMIB-FCIM-UTM.
