Fig. 4From: Photoelectrical Properties Investigated on Individual Si Nanowires and Their Size Dependencea Typical I–V curves of Si NWs with 190 nm in diameter and 800 nm in length under different laser irradiation. b SBH values obtained from the fitting of I–V curves in a. The diameter- and length-dependent SBH values under 8 W/cm2 laser irradiation are plotted in c, d, respectivelyBack to article page
