though n type conductor has large number of electrons then why it is electrically neutral?
Asked by vasturushi | 14th Nov, 2017, 09:30: PM
- n- and p-type conductor refer to the majority charge carriers.
- p and n type materials are NOT positively and negatively charged.
- An n-type material by itself has mainly negative charge carriers (electrons) which are able to move freely, but it is still neutral because the fixed donor atoms, having donated electrons, are positively charged.

- Formation of depletion layer
- What do you mean by depletion layer and potential barrier for a p-n junction.
- Can we measure the potential difference of a p-n junction by putting a sensitive voltmeter across its terminals?
- Name the different types of currents flowing through a p-n junction diode.
- a) In the depletion region of an unbiased p-n junction diode, what are the charge carriers? b)Which biasing makes the junction resistance low and which high?
- What do you understand by breakdown and breakdown voltage?
- How does an ideal diode behave when forward biased and reverse biased?
- What all techniques need to be used to obtained p-n junction?
- If the forward voltage in a semiconductor diode is changed from 1 to 2.5 V, then the forward current changes by 1.5 mA. What is the resistance of junction diode?
- Give the barrier potential of : silicon germanium
