Influence of asymmetric etching on ion track shapes in polycarbonate
By combining low-energy ion irradiation with asymmetric etching, conical nanopores of controlled geometry can be etched in polycarbonate (PC). Cone bases vary from 0.5 to 1μm. Top diameters down to 17 nm are reached.. When etching from one side, the pH on the other side (bathed in neutral or acidic buffer) was monitored. Etching temperature ranged from 65°C to 80°C. Pore shape characterization ...
متن کاملEffect of Gamma Rays on The Bulk Etching Rate of LR-115 Detector
It is important to measure the bulk-etching rate for any solid state nuclear track detectors, because they have an application in different fields of sciences. The effect of gamma rays emitted from 60 Co source with different doses on LR-115 detector was studied. The bulk etching rate of the detectors was measured before and after irradiation using gamma source. From the results the values of t...
متن کاملFaraday cage angled-etching of nanostructures in bulk dielectrics
For many emerging optoelectronic materials, heteroepitaxial growth techniques do not offer the same high material quality afforded by bulk, single-crystal growth. However, the need for optical, electrical, or mechanical isolation at the nanoscale level often necessitates the use of a dissimilar substrate, upon which the active device layer stands. Faraday cage angled-etching (FCAE) obviates the...
متن کاملInductively Coupled Plasma Etching of Bulk Titanium for MEMS Applications
Titanium is a promising new material system for the bulk micromachining of microelectromechanical MEMS devices. Titaniumbased MEMS have the potential to be used for a number of applications, including those which require high fracture toughness or biocompatibility. The bulk titanium etch rate, TiO2 mask etch rate, and surface roughness in an inductively coupled plasma ICP as a function of vario...
