| Abstract: | In this thesis, transport in Bipolar Quantum Resonant Tunneling Transistors (BiQuaRTTs) is studied. A ⁴He cryostat was built, and ³He- ⁴He dilution refrigerator was modified for this work. Preliminary results in these experiments show multiple resonant peaks in the common-emitter current voltage characteristics, but fewer of these than a different sample structure reported in a previous unpublished study. Further studies are planned for Summer 1993 to resolve several interesting effects not previously reported. |
