“…In the study of dynamic magnetotransport behaviors of low-dimensional electron systems (LDESs), such as two-dimensional electron systems (2DESs), 1,2,3,4,5 quantum wires (QWs) 6 , and anti quantum dots (QDs), 7 a microwave vector detection system, which can measure both the amplitude and the phase variations of the signals under the influence of the LDESs in magnetic fields, is indispensable. Usually people use a conventional vector network analyzer (VNA) as such a detection system by virtues of its expediency and broadband characteristics.…”

We present the design and the circuit details of a high-sensitivity microwave vector detection system, which is aiming to study the low-dimensional electron system embedded in the slots of a coplanar waveguide at low temperatures. The coplanar waveguide sample is placed inside a phase-locked loop; the phase change of the sample may cause a corresponding change in the operation frequency, which can be measured precisely. We also employ a double-pulse modulation on the microwave signals, which comprises a fast pulse modulation for gated averaging and a slow pulse modulation for lock-in detection. In measurements on real samples at low temperatures, this system provides much better resolutions in both amplitude and phase than most of the conventional vector analyzers at power levels below -65 dBm in the frequency range from 100 MHz to 18 GHz.

We present a high-sensitivity microwave vector detection system for studying the low-dimensional electron system embedded in the gaps of a coplanar waveguide at low temperatures. Using this system, we have achieved 0.005% and 0.001degrees resolutions in amplitude and phase variations, respectively, at 10 GHz in a magnetotransport measurement on a quantum-wire array with an average signal power less than -75 dBm into the sample at 0.3 K. From the measured phase variation, we can distinguish a very tiny change in the induced dipole moment of each quantum wire. (C) 2004 American Institute of Physics
