To obtain a p-type semiconductor germanium crystal, it must be doped with foreign atoms whose valency is _____?

To obtain a p-type semiconductor germanium crystal, it must be doped with foreign atoms whose valency is _____?

پی قسم کے سیمی کنڈکٹر جرمینیم کرسٹل کو حاصل کرنے کے لیے، اسے غیر ملکی ایٹموں کے ساتھ ڈوپ کیا جانا چاہیے جن کی ویلینسی _____ ہے؟
Explanation
  • P-type semiconductors are created by doping with trivalent atoms (valency 3) like boron or indium.
  • It create "holes" by accepting electrons.
  • These holes act as charge carriers, giving the semiconductor its p-type behavior.
