THz Transient Photoconductivity of the III-V Dilute Nitride GaPAsN
J. N. Heyman, E. M. Weiss, J. R. Rollag +5
THz Time-Resolved Photoconductivity is used to probe carrier dynamics in the dilute III-V nitride GaP0.49As0.47N0.036. In these measurements a femtosecond optical pump-pulse excite…
Carrier Lifetimes in a III-V-N Intermediate Band Semiconductor
J. N. Heyman, A. M. Schwartzberg, K. M. Yu +5
We have used transient absorption spectroscopy to measure carrier lifetimes in the multiband band semiconductor GaPAsN. These measurements probe the electron populations in the con…
Evidence for Macroscopic Quantum Tunneling of Phase Slips in Long One-Dimensional Superconducting Al Wires
Fabio Altomare, Albert M. Chang, Michael R. Melloch +2
Quantum phase slips have received much attention due to their relevance to superfluids in reduced dimensions and to models of cosmic string production in the Early Universe. Their…
Ultra narrow AuPd and Al wires
Fabio Altomare, Albert M. Chang, Michael R. Melloch +2
In this letter we discuss a novel and versatile template technique aimed to the fabrication of sub-10 nm wide wires. Using this technique, we have successfully measured AuPd wires,…
