Fabrication of p-Type Nano-porous Silicon Prepared by Electrochemical Etching Technique in HF-Ethanol and HF-Ethanol-H2O Solutions
Nano-porous silicon were simply prepared from p-type single crystalline silicon wafer by electrochemical etching technique via exerting constant current density in two different HF-Ethanol and HF-Ethanol-H2O solutions. The mesoporous silicon layers were characterized by field emission scanning electron microscopy and scanning electron microscopy. The results demonstrate that the width of nano-p...
متن کاملSynthesis of the Silicon Inverted Nano- Pyramid and Study of Their Self- Cleaning Behavior
In this paper, synthesis of inverted nano-pyramids on a single crystal silicon surface through a simple and cost-effective wet chemical method is surveyed. These structures were synthesized by MACE process using Cu as the assisted metal in the solution of copper nitrate, hydrogen peroxide and hydrofluoric acid for different etching times. FE-SEM images of the samples show that time is an import...
متن کاملPlasma-deposited fluoropolymer film mask for local porous silicon formation
The study of an innovative fluoropolymer masking layer for silicon anodization is proposed. Due to its high chemical resistance to hydrofluoric acid even under anodic bias, this thin film deposited by plasma has allowed the formation of deep porous silicon regions patterned on the silicon wafer. Unlike most of other masks, fluoropolymer removal after electrochemical etching is rapid and does no...
متن کاملDetermination of porous Silicon thermal conductivity using the “Mirage effect” method
Mirage effect is contactless and non destructive method which has been used a lot to determine thermal properties of different kind of samples , transverse photothermal deflection PTD in skimming configuration with ccd camera and special programs is used to determine thermal conductivity of porous silicon ps film. Ps samples were prepared by electrochemical etching. Thermal conductivity wit...
