List of experiments for the year
2011
Aim: (a) To measure
resistivity of a thin (0.5 mm) sample of Germanium as a
function of temperature by using 4-probe technique, and (b)
To estimate the bangap energy of Germanium from this
measurment.
Aim: (a) To measure
Hall voltage for a thin (0.5 mm) sample of p-doped (or
n-doped) Germanium as a function of magnetic field for
3 different sample current, and (b) to dtermine the type of
doping (i.e. n or p) from this
measurment.
Aim: To measure
magnetoresistance of a thin (0.5 mm) sample of p-doped
(or n-doped) Germanium as a function of magnetic field
for 3 different sample current.
Aim: To measure
magnetic susceptibility of a solution of a paramagnetic salt
in water for 3 different concentrations by using
Quincke's method.
Aim: (a) To create
color center in an alkaly halaid crystal by X-ray
irradiation, (b) study thermoluminescence of the color
centers as a function
of temperature.
Aim: To plot magnetic
hysteresis loop of a feromanetic rod.
Aim: To measure
dielectric constant of a ferroelectric material as a
function of temperature and to observe ferroelectric to
paraelectric transition.
Aim: To study Raman
effect in carbon
tetrachloride.
