Answer 2

Si when doped with boron is P- type semiconductor

Explanation:

• Semiconductor is of two types one is n type semiconductor, while other is P - type semiconductor.

• P- type semiconductor are those whose carrier of charge is holes.

• This P- type semiconductor obtained by doping the silicon with deficient metal like boron and aluminium then the charge flow through holes.

• N type semiconductor are those where charge carrier is mostly electron

• N type  semiconductor is obtained through doping silicon with arsenic and phosphorus
