Germanium-lead alloy with 0.3% substitutional lead formed by pulsed laser induced epitaxy

Abstract

For the first time, single crystalline GePb was formed using sputtering and laser induced epitaxy. The GePb alloy shows a good crystalline quality without Pb precipitation or clustering. No dislocation is observed at the interface between GePb and Ge. HRBS data indicates that substitutional Pb content of ~0.3% was obtained.
