Inhalt: |
A comprehensive device model considering both spatial
distributions of the terahertz field and the field-effect self-mixing factor
has been constructed for the first time in the thesis. The author has found
that it is the strongly localized terahertz field induced in a small fraction
of the gated electron channel that plays an important role in the high
responsivity. An AlGaN/GaN-based high-electron-mobility transistor with a
2-micron-sized gate and integrated dipole antennas has been developed and can
offer a noise-equivalent power as low as 40 pW/Hz1/2 at 900 GHz. By further
reducing the gate length down to 0.2 micron, a noise-equivalent power of 6
pW/Hz1/2 has been achieved. This thesis provides detailed experimental
techniques anddevice simulation for revealing the self-mixing mechanism
including a scanning probe technique for evaluating the effectiveness of
terahertz antennas. As such, the thesis could be served as a valuable
introduction towards further development of high-sensitivity field-effect terahertz
detectors for practical applications. |
