25. A strip-like conductor with dimensions a b c = 6.0.5.6 mm³ is serving as a Hall-probe.
A current of 40 mA is flowing, and the sample is placed in a magnetic field B = 0.8T, as
a result a Hall-Votlage of UH = 20 mV is measured.
a) What is the charge carrier concentration in the sample?
b) What side of the strip-like probe accumulates negative charge if the charge transport
is done via electrons?
c) What Hall-voltage arises from bipolar conduction, hence when the same amount of
electrons and holes contribute to the conduction? Electrons and hole can be assumed to
have equal mobility.

According to a new spectroscopy analysis, the adjacent bond vectors was found to be
A = 1.07i + 0.83j + 0.81k
B = 1.03i + -0.99j + -0.85k
What is the angle (in degrees) between the bonds based on this new data?
The Hall affect is used to measure the carrier
density of a thin sheet of electrons. When a
current of 80.0 µA flows through the length of
the electron sheet, which is 1.2-mm long, 0.27-
mm wide and 12-nm thick, a magnetic field
perpendicular to the sheet produces a
potential difference of 0.53 mV across the
width of the sheet. If the carrier density in the
electron sheet is 6.74 x 1025 m-3, what is the
magnitude of the magnetic field?
