Thirty molecular complexes involving quinones, halogens, polynitroaromatics, or tetracyanoethylene as electron acceptors and aromatic hydrocarbons or substituted aromatics as electron donors have been prepared and the room temperature electrical resistivities measured on compressed microcrystalline material. A lowering of electrical resistivity is generally associated with complex formation. The results are discussed in terms of crystal structure and charge transfer complex theory.
The reflectance minima associated with the free carrier plasma edges in pand n-type Bi 2 Te3 have been observed at 78° and 300 o K. The data together with the measured Hall and Seebeck coefficients have yielded combined band structure-relaxation time parameters when proper account is taken of the anisotropy. These are compared with the results of other experiments from which similar information has been obtained. For n-type Bi2Tea fair agreement is found with galvanomagnetic and optical band structure determinations. For p-type material the agreement with the results of similar experiments is considerably poorer but recent de Haas-van Alphen and galvanomagnetic measurements have established the value of the parameter measured in this experiment to within approximately the experimental error.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
