ZnO is a semiconductor material
A peculiarity of ZnO nanowire : many novel magnetic, electrical and optical properties
Various approaches of ZnO nanowire : vapor-phase method, rapid thermal evaporation, sputter deposition, template-assisted growth, chemical vapor deposition (CVD)
A vapor trapping design to modify the CVD synthesis process to facilitate and control the introduction of n-type carriers.
A p–n heterojunction composed of ZnO nanowires and a p+ silicon chip was achieved without any adulteration.
I–V curve for the p–n heterojunction composed of ZnO nanowires and the p+ silicon chip.
Au did not have any affect on the I–V curve.
the turn-on voltage of the heterojunction is about 0.5 V and the reverse sayuration current is 0.01 mA.
