Question

A long specimen of p-type semiconductor material
(A) is positively charged
(B) is electrically neutral
(C) has an electric field directed along its length
(D) acts as a dipole

Answer 1

the correct answer is option ''b''

is ellectrically neutral

Answer 2

Hey Dear,

Doping is the process of adding impurities to intrinsic semiconductors to alter their properties.

◆ Answer -

(A) is positively charged

◆ P-type semiconductor -

• Typical trivalent (column III) impurity is added to silicon/germanium.
• Usually Boron/Aluminium is used as doping material.
• Holes are the majority carriers in p-type semiconductors.

Hope this helps you. Thanks for asking..
