the gradual channel approximation shows:
shorter gate length results in higher trans conductance
Smaller gate thickness results higher trans conductance.

Yeah u r right.. But if we will take drain current equation .. There are some other factors also which depends on channel length like threshold voltage.. So what will be the exact answer ..
