Single-electron detection in a high-purity Ge device

High-purity germanium (HPGe) detectors are among the most powerful instruments for gamma ray spectroscopy, combining exceptional energy resolution with large active volumes. Although they operate close to the fundamental resolution limit at high energies, their performance at very low energies has long been limited by...

Control of disorder and superconductivity in sputtered TiN thin films via substrate RF bias

Titanium nitride thin films are prepared using DC reactive magnetron sputtering at room temperature, with an RF bias applied to the substrate to systematically control film growth. By adjusting the substrate RF bias, the degree and length scale of disorder are tuned, leading to pronounced changes in film microstructure...
