ABSTRACT
We have fabricated Si nanowires (NWs) by breaking Si-Si tip-sample junctions and studied their conductance for both p-n and p-p-type junctions at room temperature. Upon breaking the junction by retracting the Si tip from the Si clean surface, the conductance decreases by orders of magnitude from ∼1G0 to ∼10-6G0, where G0 is the quantum unit of conductance. The conductance histogram plotted against log(G/G0) reveals peaklike structures for G>10-3G0, but becomes featureless for 10-6G0
