dear shahjahan,
when p type and n type semiconductor are joined or connected it is called p-n junction...in p-n junction the holes from
p-type diffuse to n-type and vice versa....an finally a depletion layer is formed at the junction..the junction has
small p.d. called barier potential..but due to small length of depletion layer the field is very high..

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
