Abstract
A IV--IV semiconductor device having a narrowed bandgap characteristic compared to silicon and method is provided. By incorporating carbon into silicon at a substitutional concentration of between 0.5% and 1.1%, a semiconductor device having a narrowed bandgap compared to silicon and good crystalline quality is achieved. The semiconductor device is suitable for semiconductor heterojunction devices that use narrowed bandgap regions.
