Quiz

20.3.4 Using a Hall Probe – Check yourself

Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
A Hall probe reading is proportional to
the component of B parallel to the wafer
B2
the area of the field
the component of B perpendicular to the wafer
2.
When the probe is rotated, the reading is greatest when the field
is parallel to the wafer face
is at 45° to the wafer
is perpendicular to the wafer face
is zero
3.
With no field, a probe reads 0.15 mV. The best action is to
ignore it
subtract it from all readings
add it to all readings
replace the voltmeter
4.
Calibration graph of VH against B is a straight line through the origin with gradient
I/(ntq)
BI
t/(nq)
nq/(It)
5.
A probe reads 2.0 mV in a 40 mT field. The reading in a 100 mT field is
8.0 mV
0.80 mV
5.0 mV
2.5 mV
6.
A probe at 30° between the wafer plane and the field reads 1.5 mV. The reading at 90° would be
1.5 mV
3.0 mV
0.75 mV
2.6 mV
