Why NOT get is called inverter ?
Answer:- NOT gate is also called as inverter because it's output signal is just inverse of it's input signal. I.e if input signal value is ‘1’ then it's output signal value is ‘0’ or if input signal value is ‘0’ then it's output signal value is ‘1’.
What is p-n junction ?
Answer:- A p-n junction is formed when we add a pentavalent impurity in a p-type semiconductor. l.e in a p-n junction one side is p-type semiconductor & another side is n-type semiconductor with forming a depletion region in their junction. A p-n junction is symbolically represented as, A p-n junction is generally called a Semiconductor diode.
What is forward biasing ?
Answer:- In forward biasing process positive terminal of battery connected in p-side & negative terminal of battery connected n-side of semiconductor diode. positive charge are flow from positive terminal to p-side therefore holes are move towards depletion layer(due to repulsion) & negative charge are flow from negative terminal to n-side so electrons of n-side diode move towards depletion layer (due to repulsion). After some time depletion layer became diffused(cancelled out) and current flow from positive to negative terminal of battery.So current flow in only one direction in Semiconductor.The above process is known as forward biasing
What is forbidden or energy gap ?
Answer:- The gap between the top of the valence band and bottom of the conduction band is called the forbidden gap or energy gap.
