低电子温度用印刷电路板金属粉末滤波器
Printed Circuit Board Metal Powder Filters for Low Electron Temperatures
摘要：
我们报告的印刷电路板（PCB）的金属粉末过滤器的特性和它们对有效电子温度的影响，这是低至22 mK的量子点在硅MOSFET结构中的稀释制冷机。本文研究了由四种粒径小于50 μ m的金属粉末制成的滤波器的衰减特性（10 MHz- 20 GHz）。不锈钢粉末滤波器在1.5GHz以上的频率处的室温衰减大于80 dB。在所有金属粉末过滤器中，衰减随温度而增加。与经典粉末过滤器相比，这里提出的设计制造起来要轻松得多，特别是铜粉末PCB过滤器提供与经典过滤器相同甚至更好的性能。
英文摘要：
We report the characterisation of printed circuit boards (PCB) metal powder filters and their influence on the effective electron temperature which is as low as 22 mK for a quantum dot in a silicon MOSFET structure in a dilution refrigerator. We investigate the attenuation behaviour (10 MHz- 20 GHz) of filter made of four metal powders with a grain size below 50 um. The room-temperature attenuation of a stainless steel powder filter is more than 80 dB at frequencies above 1.5 GHz. In all metal powder filters the attenuation increases with temperature. Compared to classical powder filters, the design presented here is much less laborious to fabricate and specifically the copper powder PCB-filters deliver an equal or even better performance than their classical counterparts.
