Query: High Precision, Low Excitation Capactiance Measurement Methods from 10
  mK- to Room-Temperature   Capacitance measurement is a useful technique in studying quantum devices, as
it directly probes the local particle charging properties, i.e. the system
compressibility. Here we report one approach which can measure capacitance from
mK to room temperature with excellent accuracy. Our experiments show that such
a high-precision technique is able to reveal delicate and essential properties
of high-mobility two-dimensional electron systems.
