Abstract

In one aspect, a template for growing a crystal of a two-dimensional material can include a flat surface for growing the crystal thereon, a first wall on the flat surface, and a second wall on the flat surface. The first and the second walls can meet at a corner to form an angle having an opening that is adapted to align with the crystal structure of the crystal with a tolerance of up to 5°. Each of the first and second walls can have a length of from 5 nm to 1000 nm and a height of from 0.6 nm to 2 nm.
