电容测量是研究量子器件的有用技术,因为它直接探测局部粒子充电特性,即,系统压缩性。在这里,我们报告一种方法,可以测量从mK到室温的电容,具有良好的精度。我们的实验表明,这种高精度的技术能够揭示高迁移率二维电子系统的微妙和本质的属性。
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 to reveal delicate and essential properties of high-mobility two-dimensional electron systems.
