When the voltage is applied to semiconductor holes will flow
Right Answer is:
Toward negative terminal
When the voltage is applied to the semiconductor holes will flow towards negative terminal.
Forward bias is obtained with the negative terminal of the battery connected to the N-side and the positive terminal connected to the p-side.
Since the hole is a positive charge carrier and an electron is a negative charge carrier hence the negative terminal will repel free electrons in the n-section towards the junction, and the positive terminal on the p-side will push the holes towards the negative terminal junction. These free electrons and holes will then combine at the junction.
