ABSTRACTLuminescence nanocrystals or quantum dots give grate potential for bio-analysis as well as optoelectronics. Here we report an effective and non-expensive fabrication method of silicon carbide nanocrystals, with diameter below 10 nm, based on electroless wet chemical etching. Our samples show strong violet-blue emission in the 410-450 nm region depending on the used solvents and particle size. Raman and infrared measurements suggest the varied nature of surfaces of silicon carbide nanocrystals which elucidate the behavior of the silicon carbide colloid solvents and also give opportunity to modify the surface easily for specific biological, medical or other application.

The paper introduces a new design of Marx generator based on modular stages using Silicon Carbide MOSFETs (SiC-MOSFET) aimed to be used in biomedical applications. In this process, living cells are treated with intense nanosecond Pulsed Electrical Field (nsPEF). The electric field dose should be controlled by adjusting the pulse parameters such as amplitude, repetition rate and pulse-width. For this purpose, the structure of the proposed generator enables negative pulses with a quasi-rectangular shape, controllable amplitude, pulse-width and repetition-rate. A complete simulation study was conducted in ANSYS-Simplorer to verify the overall performance. A compact, modular prototype of Marx generator was designed with 1.7 kV rated SiC-MOSFETs and, finally, a set of experiments confirmed all expected features.
