Abstract: Disclosed are methods for growing Sn-containing semiconductor materials. In some embodiments, an example method includes providing a substrate in a chemical vapor deposition (CVD) reactor, and providing a semiconductor material precursor, a Sn precursor, and a carrier gas in the CVD reactor. The method further includes epitaxially growing a Sn-containing semiconductor material on the substrate, where the Sn precursor comprises tin tetrachloride (SnCl4). The semiconductor material precursor may be, for example, digermane, trigermane, higher-order germanium precursors, or a combination thereof. Alternatively, the semiconductor material precursor may be a silicon precursor.
