Rapid development of micro-and nanofabrication methods have provoked interest and
enabled experimental studies of electronic properties of a vast class of (sub) micrometer …

We are proposing a hybrid superconductor–semiconductor platform using indium arsenide
(InAs) grown on an insulating layer of indium aluminum arsenide heterostructure (InAsOI) as …

There is a growing demand for refrigeration techniques to reach temperatures below 1 K
because these temperatures are critical for a wide range of rapidly developing applications …

In the emergent field of quantum technology, the ability to manage heat at the nanoscale
and in cryogenic conditions is crucial for enhancing device performance in terms of noise …

We demonstrate significant cooling of electrons in a nanostructure below 10 mK by
demagnetisation of thin-film copper on a silicon chip. Our approach overcomes the typical …

Electrothermal elements are used in various energy harvesters, coolers, and radiation
detectors. The optimal operation of these elements relies on mastering two competing …

We demonstrate an original method based on controlled oxidation for creating high-quality
tunnel junctions between superconducting Al reservoirs and InAs semiconductor nanowires …

The surface modifications in a multilayer thin-film structure (50-nm alternating layers of Si
and Al) induced by a single Gaussian-shaped femtosecond laser pulse (350 fs, 1028 nm) in …

We demonstrate highly transparent silicon–vanadium and silicon–aluminum tunnel
junctions with relatively low sub-gap leakage current and discuss how a trade-off typically …
