Hydrogenated graphene, also known as graphane, is a wide band gap semiconductor in its various possible conformations. Here we show with first-principles calculations that application of uniaxial pressure can give rise to stripes of the so-called washboard conformation between segments of the most stable chair geometry. Compressed washboard-chair superlattices follow distinct zigzag patterns with interchanging chair and washboard parts. Hybrid systems of this type could be employed in various applications, such as in the templated growth of nanosystems, or as parts of nanomechanical systems.
氢化石墨烯，也称为石墨烷，在其各种可能的构象中是一种宽带隙半导体。在这里，我们通过第一性原理计算表明，单轴压力的施加可以在最稳定的椅式几何结构的片段之间产生所谓的搓板构象条纹。压缩的搓板-椅超晶格呈现出明显的锯齿形图案，其中交替出现椅式和搓板部分。这种类型的混合系统可以应用于各种应用，例如在纳米系统的模板生长中，或作为纳米机械系统的一部分。
