제목 Facile Release of Si Nanowires By Wet Chemical Etching Process Based On Alkali Hydroxides
초록 In this research, a simple process for releasing Si nanowires(SiNWs) and keeping their almost original length has been demonstrated. SiNWs used in this research was made by metal-assisted electroless etching process. KOH or NaOH was used for releasing the SiNWs with wet-etching process at bottom site of the SiNWs array. During the releasing process of SiNWs from the mother Si wafer substrate, the Si oxide layer existed around the SiNWs act as a etch mask from the anisotropic wet-etching process by alkali hydroxide. After releasing the SiNWs from the mother Si substrate, the mother Si wafer substrate can be recycled to fabricate SiNWs by MaCE process. The released SiNWs was tested for the field effect transistor(FET) on flexible PET substrate. If this method combined with other proper assembling thechnique, such like flexible electronics or composite with other materials, it could be very valuable for various fields.
