A cuboid of Germanium (Ge) has contacts all over its 2 x 1 mmends and point contacts exactly half way along its 5 mm length, atthe center of the 5 x 1mm faces. A magnetic field can be appliedparallel to this face. A current of 5mA is passed between the endcontacts of 4.8 mV with no magnetic field.
(i) Using the corrected Hall voltage find the carrier density in the Ge sample.
(ii) Estimate the conductivity of the Ge.
(iii) What is the mobility of the carriers?
(iv) Is it a p or n type semiconductor?
