Electrical resistivity and thermoelectric power measurements
have been made over the temperature range of 450° to 600°C on
n-type liquid thalliurn-tellurium solutions. Liquids with compositions
from 61.5 to 72.0 atomic percent thallium were studied. In addition,
alloys of some of the three component thallium-teIlurium solutions
containing small amounts of silver,...
The longitudinal magnetoresistance of single-crystals of
mercury is investigated experimentally, both in the low field and
the high field regions. The variation of the magnetoresistance with
crystal purity, orientation, size and temperature below 4.2°K is
presented. In the low field region the data are discussed in terms
of existing theory....
Density measurements of molten solutions of thallium
and tellurium have been made over the temperature range
220 to 650°C and the composition range 31 to 69 atomic
per cent thallium. The Archimedian method was employed
since it is readily adaptable to performing measurements
over wide ranges of temperature and composition...
Measurements are made of the conductivity and Hall mobility of
liquid solutions of thallium-tellurium, in compositions ranging from
pure tellurium to 69.0 atomic percent thallium. At compositions on
the thallium-rich side of intrinsic composition (66.7 atomic percent
thallium) both the conductivity and Hall mobility are temperature
independent, and the data...
A great concern about the effect of oxygen in Se samples has been solved by a purification method called the distillation-with-Al method. The electrical conductivity of liquid Se prepared by this purification method shows Arrehnius behavior with a single activation energy and positive thermopower within the experimental temperature range. This...
