365579 The hole in a \(p\)-type semiconductor is

1 An electron deficiency
2 An electron excess
3 An atom deficiency
4 Positive ion
PHXII14:SEMICONDUCTOR ELECTRONICS- MATERIALS- DEVICES AND SIMPLE CIRCUITS

365580 The mobility of free electrons is greater than that of free holes because

1 They carry negative charge
2 They are light
3 Their mutal collisions are less
4 They require low energy to continue their motion
PHXII14:SEMICONDUCTOR ELECTRONICS- MATERIALS- DEVICES AND SIMPLE CIRCUITS

365581 In \(n\)-type semiconductor when all donor states
are filled, then the net charge density in the donor states becomes:

1 1
2 \(>1\)
3 \( < 1\), but not zero
4 Zero
PHXII14:SEMICONDUCTOR ELECTRONICS- MATERIALS- DEVICES AND SIMPLE CIRCUITS

365582 The electron concentration in an \(n\)-type semiconductor is the same as hole concentration in a \(p\)-type semiconductor. An external field (electric) is applied across each of them. Compare the currents in them:

1 Current in \(p\)-type > current in \(n\)-type.
2 Current in \(n\)-type > current in \(p\)-type.
3 No current will flow in \(p\)-type, current will only flow in \(n\)-type.
4 current in \(n\)-type = current in \(p\)-type.
