One-step metal-assisted electroless chemical etching of p-type silicon substrate in NH4HF2/AgNO3 solution was investigated. The effect of different etching parameters including etching time, temperature, AgNO3 concentration and NH4HF2 concentration were investigated. The etched layers formed were investigated by scanning electron microscopy (SEM) and Photoluminescence. It was found that the etched layer was formed by well-aligned silicon nanowires. It is noted that their density and length strongly depend on etching parameters. Room temperature photoluminescence (PL) from etched layer was observed. It was observed that PL peak intensity increases significantly with AgNO3 concentration.

AbstractThe present work discusses the systematic study of mechanical properties of the silicon nanostructures formed by metal assisted chemical etching (MACE). Silver electrolyte solution, along with hydrogen fluoride, was utilized in formation of silicon nanostructures. An optimized condition of etching time and silver electrolyte concentration were utilized to obtain high aspect ratio, defect-free and high density nanowire arrays on Si wafers. The as-prepared silicon nanostructures (SiNS) were investigated by Scanning electron microscopy (SEM) and nano indentation technique to bring out the morphological and mechanical properties. Further, the variation in optical properties of the bulk silicon and Si nanowire arrays were also investigated to determine the formation of nanostructures.

Chip Size

The fabrication procedure of silicon nanowire thermoelectric device has been developed based on the electroless etching method. Under a fixed etching solution concentration ratio and the etching reaction temperature, silicon nanowire arrays of different lengths manufactured at different etching time were investigated. The longer etching time results in the longer nanowire length. The silicon nanowire arrays were utilized to produce a silicon nanowire thermoelectric device. The I-V characteristics of the present SiNWs thermoelectric device were recorded under different heating temperatures, and the power outputs of silicon nanowire thermoelectric devices were calculated. The longer the silicon nanowire thermoelectric device lines, the greater the power output of thermoelectric device is. The SiNWs TED power output in the present study ranges from 1.62 to 7.2 nano-Watt with the chip size 2×2 cm2 while the applied temperature at 150 °C.

Traditional Approaches

A novel two-stage technique to fabricate silicon nanoparticles is reported. At the first stage, silicon nanowire arrays are formed by metal-assisted chemical etching. At the second stage, the nanoparticles are produced by pulsed laser ablation of the silicon nanowire targets in water and ethanol. The fabricated particles have relatively small mean size in the range of 24 – 45 nm depending on the used buffer liquid. The ablation threshold of the silicon nanowire arrays is 2 – 11 times smaller than that for crystalline silicon targets. Owing to the achieved parameters, the proposed technique is more efficient in comparison with traditional approaches of mechanical milling of silicon nanowires and laser ablation of crystalline silicon. Raman spectroscopy study revealed crystalline structure of the fabricated silicon nanoparticles. The properties of the produced nanoparticles indicate their high potential in biophotonics.
