项目摘要
We develop a novel method for refrigeration using helium isotope mixture liquid(^3He-^4He) in nanoporous media, and study the spintronic properties of helium-3 quasiparticles. Porous alumina substrates in which the pore size is narrowed by plating gold are successfully prepared. Measurements of superfluid properties of confined liquid^4He showed the reduction of pore size down to 10 nm. We pursue these methods to decrease the pore size down to 5 nm, at which the energy quantization of^3He quasiparticles and refrigeration are expected.
我们发展了一种利用氦同位素混合液(^3He-^4He)在纳米多孔介质中制冷的新方法,并研究了氦-3准粒子的自旋电子学性质。成功地制备了多孔氧化铝基板,其中孔径通过镀金而变窄。对受限液体^[4] He超流性质的测量表明,其孔径减小到10 nm。我们采用这些方法将孔径减小到5 nm,在此孔径下,^3He准粒子的能量量子化和制冷是有希望的。
