The probability is

See the step by step solution

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
