Fig. 4: Crystallographic microstructures.
From: A scheme for simulating multi-level phase change photonics materials
a Crystallographic microstructures at different laser power. First row: simulation; Second row: experiments. The scale bar is 200 nm. b Mean diameters of crystallised regions at different laser powers. The dashed green line indicates the FWHM of the laser beam. c Histogram of the crystallised mark diameters, which was simulated for an incident laser power of 3.8 mW.
