Electronic-controlling nanotribological behavior of textured silicon surfaces fabricated by laser interference lithography

Abstract

The electronic-controlling nanotribological behavior of textured silicon surfaces was investigated by an atomic force microscope (AFM), which were fabricated by laser interference lithography and chemical etching. The results indicated that without an external bias, friction on textured surfaces was greater than that on smooth surfaces and it was related to the coverage rate of the microgrooves. With an external bias, friction on smooth and textured surfaces decreased at first and then increased approximately linearly as the external bias increased.

Electronic Controlling on Nanotribological Properties of a Textured Surface by Laser Processing

“…Except for a wide range of other applications of laser technique [2][3][4], as an effective technique, it also was used to improving the coating performances [5][6][7][8]. Many researchers have investigated the laser processing technique about how to improve surface performance of alloy coatings [9][10][11]. Nowadays, methods such as moulding [12], electrochemical deposition [13,14], and chemical vapor deposition [15] are used to produce artificial surfaces with particular textures.…”
