Conclusion, Acknowledgements, and References B. Log-normal work function distribution Next we consider log-normal distribution for the work function. In Fig. 8 we show the histogram plot of the work function, sampled over log-normal distribution for four choice of median work function M ≡ e µ = 3.0, 3.5, 4.0 and 4.5 eV with σ = 0.05. From this plot we can see that our choice of random variables for Φ are well sampled over the log-normal distribution. 1. Case with Φ ≪ EF 2. Case with Φ ≫ EF V.

P) would like to thank IIT, Kharagpur for local hospitality where part of the work was done. One of us (R.
