The potential difference created across the P-N junction due to the diffusion of electron and holes is called potential barrier.
For and for silicon
On the average the potential barrier in P-N junction is ~ 0.5 V and the width of depletion region ~ 10-6.
So the barrier electric field.
derive an expression for the total cross section for the scattering of light by a polorisable molecule in term of the incedent wave length.
In isobaric process pressure of the gas is constant overall the process. As, V/T is constant in isobaric process.
What i the name given to that kind of electromagnetic spectrum which is used for taking photographs of earth under foggy conditions from great heights?
Uses of Radio Isotopes: Industries: 1. Radio active isotopes are used to detect leakage in pipes. 2. It estimates weak and tear machine tools. 3. It is used to check t
A charge q1 is 9.00um is at the origin, and a charge q2 is -4.00um is on the x- axis 0.30m from the origin. find the electric field strength at point P, which is on the y - axis 0.
A charge Q is to be distributed between the objects . what should be the magnitude of the charge on the object so that positive force between the object is maximum?
Neutron is a fundamental particle carrying: (1)A charge of +1 unit and a mass of 1 unit (2)No charge and a mass of 1 unit (3)No charge and no mass (4) A charg of -1
Details about halls effect
Suppose that we have a monochromatic non-diverging beam of x rays that are incident on a slab of Pb. Inside the Pb plate there are three apertures (openings) that allow the beam
