Until recently, the lowest temperature ever reached in such systems was around 4 millikelvin. Here, a temperature of 1.2mK is reported in a nanoelectronic device. The thesis introduces the idea that on-chip demagnetization refrigeration can be used to cool a wide variety of nanostructures and devices to microkelvin temperatures. This brings the exciting possibility of discovering new physics, such as exotic electronic phases, in an unexplored regime and the potential to improve the performance of existing applications, including solid-state quantum technologies. Since the first demonstration of on-chip demagnetization refrigeration, described here, the technique has been taken up by other research groups around the world. The lowest on-chip temperature is currently 0.4mK. Work is now underway to adapt the technique to cool other materials and devices, ultimately leading to a platform to study nanoscale materials, devices and circuits at microkelvin temperatures. . 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aLow temperature physics 606 $aLow temperatures 606 $aMaterials science 606 $aSolid state physics 606 $aLow Temperature Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P25130 606 $aMaterials Science, general$3https://scigraph.springernature.com/ontologies/product-market-codes/Z00000 606 $aSolid State Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P25013 615 0$aLow temperature physics. 615 0$aLow temperatures. 615 0$aMaterials science. 615 0$aSolid state physics. 615 14$aLow Temperature Physics. 615 24$aMaterials Science, general. 615 24$aSolid State Physics. 676 $a536.56 700 $aJones$b Alexander Thomas$4aut$4http://id.loc.gov/vocabulary/relators/aut$0861753 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a996418176303316 996 $aCooling Electrons in Nanoelectronic Devices by On-Chip Demagnetisation$91923109 997 $aUNISA
