Future trends in power electronic devices

BĂJENESCU, Titu-Marius I. (Technical University of Moldova, 2019)

The recent technological progress of semiconductors and increasing demand for power electronic devices in the different domains of electric energy particularly for applications in aeronautics and networks of transport and ...
Microheaters for copper oxide-based gas sensors

ABABII, Nicolai; TROFIM, Viorel; LUPAN, Oleg (Tehnica UTM, 2020)

This paper describes two procedures developed for obtaining microheaters for copper oxide-based gas sensors. Different types of substrates (glass, SiO2/Si and ceramic) are investigated, as well as different configurations ...
Quantum treatment of self-organization phenomena of excitons and biexcitons

CIOBANU, Nellu; ROTARU, Anatol; GONTIA, Ilarie; TRONCIU, Vasile (Technical University of Moldova, 2019)

We present in this paper the quantum treatment of self-organization phenomena of excitons and biexcitons in the geometry of a ring cavity. Applying the adiabatic elimination method of the exciton and biexciton variables, ...
Some reliability aspects of MEMS and NEMS manufacturing

BĂJENESCU, Titu-Marius I. (Technical University of Moldova, 2021)

A full understanding of the physics and statistics of the defect generation is required to investigate the ultimate reliability limitations of manufacturability of MEMS and NEMS. In order that the user can include electronic ...
