High precision, low excitation capacitance measurement methods from 10 mK to room temperature
High precision, low excitation capacitance 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 that can measure capacitance from mK to room temperature with excellent accuracy. Our experiments show that such a high-precision technique is able …
