Why n-Channel MOSFET is Widely Used Than p-Channel MOSFET?

  If you say n-channel it is made up of Silicon.
  Silicon has high power handling capacity. So probably that is one of the reason.

  I think it has more to do with the channel width between the source & drain in a n-channel MOSFET than a p-channel MOSFET.

  Hi,
  
  NMOS - the carriers are electrons and so higher velocity and hence much faster.
  PMOS - Holes --> heavier than electrons --> Slower speed.
  
  For same speed, the size of PMOS should be much more than nmos ==> Density reduction
  
  All logics can be implemented just with the use of NMOS.
  
  Just for clarification - both nmos and pmos are made of Silicon substrate, its only that the dopants vary.!!
  
  Cheers,
