We used gold nanoparticles (AuNPs) which has low eutectic temperature, such as a metal catalyst in Vapor Liquid Solid (VLS) method to grow SiNW on top of Silicon 〈100〉 substrates. AuNPs are synthesized using Turkevich method and then deposited on the Silicon substrate using dip coating method. To grow SiNWs, we placed the sample inside a Low Pressure Chemical Vapor Deposition (LPCVD) reactor with temperature around the Si-Au eutectic temperature (∼500°C), after the temperature is stable we flowed Silane (SiH4) gas diluted in Nitrogen gas to the chamber for several minutes. We found that the SiNWs are grown with AuNPs as the nanowire cap on the top of it. SiNWs have an average length around 500-800 nm with diameter proportional to its gold catalyst. By optimizing the growth parameter, we aim to achieve vertical SiNWs that can be used for practical devices such as chemical sensors. © 2011 American Institute of Physics.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Gold nanoparticles,LPCVD,Silicon Nanowires,Vapor-Liquid-Solid[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1063/1.3667214[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
