p type of semiconductor is obtained when Silicon is doped with a trivalent impurity like Aluminium. Aluminium is a p-type dopant, which means that when a semiconductor i.e. silicon is doped with aluminium, it creates a hole (positively charged carrier) by accepting an electron from the silicon atom. Electrical conductivity of semiconductors increasesand resistivity remains the same

A Dice has 6 faces with 1 - 6 number of dots one on each side.

So in total 1 + 2 + 3 + 4 + 5 + 6 = 21 dots resembles as eyes.
