Investigation of electronic and structural properties of silicon solar cell contacts... The results show that in under fired cells the PFT was too low to etch away the SiN layer which works as an insulating layer and impedes current collection....
Type- and species-selective air etching of single-walled carbon nanotubes tracked with in situ raman spectroscopy... Changes to radial breathing mode (RBM) and G– peak structures suggest that metallic species etch away more rapidly, with smaller diameter semiconducting species etching more slowly and large diameter nanotubes, including semiconductors, etching last....
Surface science letters linking dislocation dynamics and chemical reactivity on strained metal films... With the addition of more oxygen, the mesoscopic structure of the film changes from a striped array of Shockley partials to a disordered array of triangular fcc regions bounded by dislocations, as oxygen proceeds to etch away the hcp areas of the copper film....
Rotating actuators mechanical...(e.g., CMOS, Bipolar, or BICMOS processes), The micromechanical components are fabricated using compatible “micromachining " processes that selectively etch away parts of the silicon wafer or add new structural layers to form the mechanical and electromechanical devices....
