Heteroepitaxial growth oscillations of the 20L CTR at L = 0.5 during the growth of a 25 unit-cell-thick PbTiO3 film on SrTiO3 under step-flow growth conditions [T = 969 K, TTB:TEL = 1.6:1, growth rate = 0.016 unit cell s−1, miscut = 0.23° (100 nm step spacing)] measured at α = αc. Vertical dashed lines indicate the beginning and end of growth. |
