For our chunk o’ GaN in Question 1 Find the average time between collisions for holes. For a 6 cm long sample with A=1cm, if a voltage of 25V is placed across opposite surfaces, what will be the current density? For this same current (from B) is used in a Hall effect measurement and the Hall electric field was found to be 87.5 V/cm, what magnetic field B was used?
