From: Thermally controlled widening of droplet etched nanoholes
Cross-sectional schematic of the proposed mass transport leading to thermally widened nanoholes shown in (c). In (a), the length of the arrows qualitatively represent the magnitude of material evaporation rates from various positions on the surface of a droplet etched nanohole. Similarly, in (b), the length of the arrows qualitatively represent the magnitude of diffusive flux across the surface.
