Abstract
We have studied the (I-V) characteristics of the tunnel junction formed between the tip and the substrate in an STM at room temperature. We find that in such an arrangement it may be possible to get a junction capacitance ⋍10−19 F and junction conductance < 1 μs. When the junction conductance is < 1 μs strong nonlinearity is observed in the (I-V) characteristics. We explain this nonlinearity as onset of coulomb blockade of tunneling electrons.
