Exergy analysis and sensitivity study of a PV/T -air source heat pump coupled heating system under cold climates

Photovoltaic/thermal (PV/T) and air source heat pumps (ASHP) are widely recognized as promising clean heating technologies to achieve carbon neutrality in building sectors. Nevertheless, their large-scale application is severely restricted by solar intermittency and ASHP frosting...

An engineered metal-to-insulator transition in a two-dimensional network of degenerate phosphorus quantum dots in silicon

Phosphorus quantum dots (QDs) in silicon are a prominent candidate for semiconductor quantum computing based on donor spins. In this work, we report the formation of degenerate phosphorus QDs with a radius of 3 nm confined in a two-dimensional plane in silicon. A multilayer of Si...
