摘要:

吸附在二维材料上的向列型液晶(LC)分子沿六方晶格的晶体方向排列。结果表明,短脉冲可以使取向的液晶分子沿六方氮化硼(h-BN)的优先扶手椅方向重新取向。通过改变电脉冲的方向和强度,得到了具有各种颜色的几种状态。采用基于密度泛函理论的从头计算方法研究了液晶分子在h-BN表面的吸附构型。提出了一种非易失性显示器,其中像素分辨率可以由六边形表面的晶粒来确定,这可以提供一种以低功耗实现动态高质量像素的途径,并且可以为所有非易失性显示器应用定义新的范例。

英文摘要:

Nematic liquid crystal (LC) molecules adsorbed on two dimensional materials are aligned along the crystal directions of the hexagonal lattice. It was demonstrated that short electric pulses can reorient the aligned LC molecules in the preferred armchair direction of hexagonal boron nitride (h-BN). Several states with a variety of colors were obtained by changing the direction and strength of the electric pulses. The ab initio calculations based on density functional theory was carried out to determine the favorable adsorption configurations of the LC molecules on the h-BN surface. A non-volatile display, in which pixel resolution can be determined by grains of hexagonal surface, is proposed, which can offer a pathway towards dynamic high-quality pixels with low power consumption, and could define a new paradigm for all non-volatile display applications.
