An embodiment provides a method for selectively depositing a single crystalline film. The method includes providing a substrate, which includes a first surface having a first surface morphology and a second surface having a second surface morphology different from the first surface morphology. A silicon precursor and BCl3 are intermixed to thereby form a feed gas. The feed gas is introduced to the substrate under chemical vapor deposition conditions. A Si-containing layer is selectively deposited onto the first surface without depositing on the second surface by introducing the feed gas.
