This work presents the first high-resolution nanoprofilometry study consisting of nanoscale resolution surface profile measurements and high-quality visualization of a the free surface of a liquid crystal-air boundary. The capabilities of this new experimental method, as applied for liquid crystal free boundaries, are discussed. The formation of focal conic domain structures at the smectic-A-air free boundary was detected and studied.
这项工作展示了首个高分辨率纳米轮廓测定研究，该研究包括纳米级分辨率的表面轮廓测量以及液晶 - 空气边界自由表面的高质量可视化。讨论了这种应用于液晶自由边界的新实验方法的能力。检测并研究了近晶A - 空气自由边界处焦锥域结构的形成。
