Examples of micro- and nano-fabrication.
RIE dry etching of GaN
by Rafal Dylewicz
This gallery shows some of my recent work related to the material engineering (micro- and nano-technology) for scientific purposes (photonics and optoelectronics), as well as work towards theoretical simulations of device performance. Pictures were taken by scanning electron microscopy (SEM).  References:
