We urgently request funding for the acquisition of a second-hand microwave source. This is the consequence of two major breakthroughs in Gervais' laboratory. The first concerns the fabrication of vertically-coupled quantum wire circuits designed with independent contacts [a NSERC DG funded project]. Last year, we successfully measured the 1D-1D "Coulomb drag signal"; i.e. the voltage generated in one wire by the current flow in the other owing to the close proximity (less than 15 nm) between the two quantum wires. These results were published in the journal Nature Nanotechnology in 2011. We are now intensively investigating electron-electron interaction in our coupled 1D-1D devices at the lowest temperatures where it is expected that a Luttinger liquid will form. In order to elucidate this physics, a microwave source in the GHz range is urgently needed. Second, we have recently (2012) filed a US patent regarding the direct cooling of silicon "all-on-a-chip''. The demonstration of magnetic refrigeration in doped silicon presents several interesting new technological avenues. Our technique allows for seamless, monolithic integration of refrigerant with active electronic devices built in modern foundries. In the future, this could prove important for refrigeration of electronics for applications such as quantum devices, quantum information, as well as low-noise detector arrays. In order to push our concept further, we urgently need a microwave source to perform electrically detected electron spin resonance (ESR) on the donour bound spins. Finally, in order to limit the cost and the burden on the NSERC RTI program, we propose as a realistic solution to purchase a second-hand microwave source for less than 40% of the cost of a brand new microwave source.

我们紧急请求资金购买二手微波源。这是热尔韦实验室两项重大突破的结果。第一个涉及采用独立触点设计的垂直耦合量子线电路的制造[NSERC DG 资助的项目]。去年，我们成功测量了1D-1D“库仑阻力信号”；即，由于两条量子线之间距离很近（小于 15 nm），另一根导线中的电流在一根导线中产生电压。这些结果发表在 2011 年《自然纳米技术》杂志上。我们现在正在深入研究耦合 1D-1D 器件在预计形成 Luttinger 液体的最低温度下的电子-电子相互作用。为了阐明这一物理现象，迫切需要 GHz 范围内的微波源。其次，我们最近（2012 年）申请了一项关于硅“全芯片”直接冷却的美国专利。掺杂硅中磁制冷的演示提出了几种有趣的新技术途径。我们的技术允许无缝、未来，制冷剂与现代铸造厂建造的有源电子设备的单片集成对于量子设备、量子信息以及低噪声探测器阵列等应用的电子设备的制冷非常重要。此外，我们迫切需要最后，为了限制 NSERC RTI 计划的成本和负担，我们建议购买二手微波源作为一个现实的解决方案。成本不到全新微波源的 40%。
