Figure 5: Sample growth.
From: Electronic phase separation at the LaAlO3/SrTiO3 interface
RHEED data for samples prepared at oxygen partial pressure (PO2) of (a) 1×10−4 mbar and (b) 1×10−2 mbar show clean oscillations that indicate 2D growth. (c) A deformed RHEED oscillation for a sample grown at 5×10−2 mbar indicates commencement of a 3D growth process.
