- •
CdTe(111) films are epitaxial on highly mismatched STO(001) substrates by MBE.
- •
Atomic flat surface is confirmed as the thickness of the CTELs is below ∼40 nm.
- •
A FWHM of ∼110 arcsec is yielded when the thickness of CTELs is beyond ∼100 nm.
- •
φ-scan illustrates the appearance of four types of domains in the CTELs.
- •
Direct band transition is confirmed, and shrinks with increasing temperature.
