What is the probability that an electron will tunnel through a gap from a metal to a STM probe if the work function is ?

The probability is

See the step by step solution

Step 1: Given information

We have given,

Work function =

penetration depth =

We have to find the probability of tunneling.

Step 2: Simplify

We know the penetration depth can be written as ,

substitute the all value

and we know the probability
