| 英文摘要 | Photocurrent transient variation caused by hot-electron transfer was detected in gold nanoparticles embedded in silicon nanowire field-effect transistors via their electrical response under illumination. The devices showed dramatic photocurrent transient variation at various illumination wavelengths (300, 500, 700, and 900 nm). The maximum transient variation of the source-drain current was about five-fold stronger with the gold nanoparticles than without. A finite-difference time-domain method was employed to determine the response wavelength range of the photocurrent transient variation. The distribution of the local electromagnetic field at the interface of the gold nanoparticles and the silicon nanowire was calculated. The weak hot-electron transfer for incident wavelengths below 500 nm was concentrated on the three-phase boundary of air, gold, and silicon, while there was a relatively strong hot-electron transfer present at the boundary of gold and silicon in the wavelength range from 700 to 900 nm.
