Abstract : This Technical Report summarizes the results of a three-year research effort in the field of mesoscopic physics conducted by John M. Hergenrother at Harvard University, supported by a JSEP Fellowship. During the first two years, Hergenrother was a graduate student; during the final year, he was a postdoctoral research associate. The results have been reported in 11 publications which are listed in the Report. The primary focus of the work was charge transport in single-electron tunneling transistors, with both normal and superconducting leads. This work illuminated the role of Andreev tunneling processes in transferring pairs of electrons from normal to superconducting electrodes, the importance of the Coulomb blockade for Cooper pairs of electrons, and the possibility of developing an ultrasensitive microwave detector capable of detecting individual photons of frequency above 80 GHz.
