Periodic nano/micro-hole array silicon solar cell. [PDF]
Nanoscale Res Lett, 2014 Abstract In this study, we applied a metal catalyst etching method to fabricate a nano/microhole array on a Si substrate for application in solar cells. In addition, the surface of an undesigned area was etched because of the attachment of metal nanoparticles that is dissociated in a solution.

Advances in the Micro-Hole & Strip Plate gaseous detector [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2003 We report on the performance of a new gaseous electron multiplier: the Micro-Hole & Strip Plate (MHSP). It consists of two independent charge-amplification stages in a single, double-sided micro-structured electrode, deposited on a thin insulating substrate. Charge gains in excess of 10 3 were obtained in a MHSP operated with soft X-rays in Ar/CO2 (70/
