On the Formation of Black Silicon Features by Plasma-Less Etching of Silicon in Molecular Fluorine Gas [PDF]

Nanomaterials, 2020
In this paper, we study the plasma-less etching of crystalline silicon (c-Si) by F2/N2 gas mixture at moderately elevated temperatures. The etching is performed in an inline etching tool, which is specifically developed to lower costs for products ...

Pyrolytic carbon coated black silicon. [PDF]

Sci Rep, 2016
AbstractCarbon is the most well-known black material in the history of man. Throughout the centuries, carbon has been used as a black material for paintings, camouflage and optics. Although, the techniques to make other black surfaces have evolved and become more sophisticated with time, carbon still remains one of the best black materials.

Bactericidal activity of black silicon. [PDF]

Nat Commun, 2013
Black silicon is a synthetic nanomaterial that contains high aspect ratio nanoprotrusions on its surface, produced through a simple reactive-ion etching technique for use in photovoltaic applications. Surfaces with high aspect-ratio nanofeatures are also common in the natural world, for example, the wings of the dragonfly Diplacodes bipunctata. Here we

Electroosmotic Flow in Microchannel with Black Silicon Nanostructures. [PDF]

Micromachines (Basel), 2018
Although electroosmotic flow (EOF) has been applied to drive fluid flow in microfluidic chips, some of the phenomena associated with it can adversely affect the performance of certain applications such as electrophoresis and ion preconcentration.

Black silicon as a platform for bacterial detection. [PDF]

Biomicrofluidics, 2015
Surface-enhanced Raman scattering (SERS) shows promise for identifying single bacteria, but the short range nature of the effect makes it most sensitive to the cell membrane, which provides limited information for species-level identification. Here, we show that a substrate based on black silicon can be used to impale bacteria on nanoscale SERS-active ...
