in case p type semiconductor mosfet the carriers are holes whose mobility is much less then electrons hence they are not used.
when mosfets were introduced originally PMOS was much more common than NMOS, because process for PMOS devices was simpler. but as process methods improved things transitioned to NMOS due to higher speed of operation due to greater carrier mobility (as explained above) and eventually CMOS due to lower power consumption.
The same was true for similar reasons with bjts: PNP was easier to make but NPN was faster.

Why do you use semiconductors while the conductors are in use?
Semiconductors might sound somewhat 'inferior' in comparison to 'conductors', but they are - due to their unique properties - indispensable in modern electronics. Semiconductors, generally, make it easily possible to control the direction and flow of electric current which is the basis of most modern electronic device.
Devices which use semiconductors use current to operate than those which do not use semiconductors?
less
What are using semiconducter?
Computer use semiconductors all machine with microchips use semiconductors
How do you keep mosfet from overheating i use only mosfet and control it using variable resistor it works but it gets overheated and brokedown.My battery operated scooter is 24v dc 72 amp.thank you.?
Use a mosfet driver instead of a simple resistor. Using a resistor to control the mosfet is a bad idea anyways because you will have terrible control (mosfets are voltage controlled. Take a look at the response curve for your mosfet). If your mosfet is fully on, its ratings may be too low for continuous operation or the power dissipation is too low for the transition between off an on an that is killing your mosfet.
Use uc3707n FOR 500W mosfet power amplifier circuit diagram?
not yet
Boron and antimony might be good elements to use as?
Semiconductors!!
Why do we mostly use indirect semiconductors?
The indirect band gap semiconductors like silicon and germanium are mostly used because they are elemental, plentiful, and easier to process than the direct band gap semiconductors which are alloys or compounds.
What is a good example of a non insulator?
There are conductors, semiconductors and insulators. Conductors and semiconductors could be considered noninsulators, so I would say copper but if you want to use semiconductors instead you can say something like doped gallium.
What is the use of load line?
It helps us to select the Q - point of the BJT, MOSFET etc.
What are devices that use semiconductors to produce electricity from solar energy?
Photovoltaic cells
Devices that use semiconductors to produce electricity from solar energy are?
Photovoltaic cells
Why we can't use silicon and germanium in laser diode?
becoz Si and Ge are indirect bandgap semiconductors. for lasing action direct bandgap semiconductors are required of the type In Ga As P
