Some Important Contributions
"Theory of Impurity Scattering," Phys. Rev. 77: 388 (1950), with V.F. Weiskopf.
"Electrical Properties of N-type Germanium," Phys. Rev. 93: 693 (1954), with P.P. Debye.
This was the first paper to give the theory of ionized impurity scattering,
which is important for understanding the mobility of semiconductors.
"Properties of Silicon and Germanium," Proc. IRE 40: 1327 (1952) and Proc. IRE 46: 1281 (1958).
This set forth the relevant theory and compared it with experimental data. It set the pattern for the understanding of mobility and Hall data in n-Ge as a function of doping.
"Impurity Band Conduction in Germanium and Silicon," Physical Review 103: 51 (1956).
These were review articles in the first and second IRE issues on the
transistor and, as such, had significant influence on the development of the field.
This was important in establishing the existence of the impurity band and predicted many of the properties later studied extensively.
"Scattering of F Hot Carriers in Ge," J. Phys. Chem. Solids 15: 208 (1960), with A.L. Brown.
"Soliton Diffusion in trans-polyacetylene", Phys. Rev. Lett. 58: 258 (1987), with S. Jeyadev.
This was the introductory paper to a large number of papers on hot carriers done in the period 1952-1965,
including the effect of carrier heating on Hall effect in p-Ge, high frequency conductivity and dielectric constant,
galvanomagnetic effects, recombination, the phonon distribution, etc. This work, and that of others, was summarized
in my monograph High Field Transport in Semiconductors, Academic Press, 1969.
This book is still a standard reference in the field.
"Soliton Mobility in trans-polyacetylene", Phys. Rev. B36: 3284 (1987), with S. Jeyadev.
"Effect of interchain coupling on conducting polymer luminescence: Excimers in derivatives of poly(phenylene vinylene)",
Phys. Rev. B56: 10060 (1997), with M. W. Wu.
- First calculations of drift mobility of solitons along a polymer chain with phonon and defect scattering;
results agree with experiment.
"Mean free time for excimer light emission in conjugated polymers", B57: 14200 (1998).
- Derivations of basic properties of excimers in conducting polymers showing the effect of the polymer
disorder on photoluminescence and the factors that determine the radiative rate.
