Twisting 2-D materials uncover their superpowers

Two-dimensional (2-D) materials, which consist of a
single layer of atoms, have attracted a lot of attention since the
isolation of graphene in 2004. They have unique electrical,
optical, and mechanical properties, like high conductivity,
flexibility and strength, which makes them promising materials for
such things as lasers, photovoltaics, sensors and medical
applications.
