Etched pores
Webing conditions will produce superficial pores with sizes which are small compared with the cell dimensions. The SSNTDs were etched in NaOH/ethanol in the end because Li et al. (2006) found that the NaOH/ethanol-etched CR-39 SSNTDs are more biocompatible than the NaOH/H2O-etched CR-39 SSNTDs. To characterize the surface topography of the ...

WebOct 3, 2014 · Large-scale self-aligned GaAs nanowire arrays were successfully fabricated by the anodic etching of an n-type GaAs (111)B substrate. Although pore generation occurred randomly at the early stage of anodic etching, homogeneous pore growth with a high pore density was accomplished spontaneously on the entire surface of the substrate by … WebJun 1, 2001 · (A) Etched pore geometry to a first approximation. The pore shape (a cone) is determined by the chemical dissolution along the particle track at a rate V T and general attack on the etched surface and on the interior surface of the etched track at a lesser rate V B (Fleischer et al., 1975). (B) Pore shape on a submicroscopic scale.
