MOSFET commutation problem

MOSFET commutation problem

I have a problem with the MOSFET commutation. The fall time is very slow when the load resistor has a low value. It seems like there's a capacitor. However, this doesn't happen when I use a BJT transistor instead of a MOSFET.
I've tried with lots of MOSFETs but the result is the same. I read this may occur because of the scope probe although I'm not sure how. Can anyone help me?
