- When Describing Semiconductor Transport The Behaviour Of A Nearly Full Band Of Electrons Can Be Equivalently Described 1 (28.04 KiB) Viewed 14 times
When describing semiconductor transport, the behaviour of a 'nearly-full band of electrons can be equivalently described in terms of positively charged 'holes'. Examine the cases of a full and nearly-full band of electrons to demonstrate how this comes about, using equations to support your answer. [4] 10 With the aid of a schematic energy band diagram of a p-n junction, explain what drift and diffusion' currents are and how they are related in equilibrium conditions. What happens when a 'forward' bias is applied across the junction? [4]
