Abstract :
In this study, we investigate the effect of annealing a sample on the microscopic variation of the bulk electronic properties of nanoscaled pn junctions formed on an Si(001) surface, with the use of STM/STS. All experiments were performed on nanoscaled planar pn junctions formed on p-type Si(001) substrates, in which BF2 ions were implanted to increase the carrier concentration after their surfaces were covered with oxide layers 5 nm thick
