Ever since the discovery of one-atom-thick graphene back in 2004 using scotch-tape exfoliation technique, the field of two-dimensional materials (2DM) has been exploding with untapped technological and fundamental potential. The ability to freely and precisely manipulate of these atomically thin materials is required to unlock the full potential of 2DM, but it still remains an outstanding challenge. Our team aims to address this important challenge by mastering the level of manipulation of 2DM, including (but not limited to):

(i) gaining a precise control over various degrees of freedom, particularly the
ability to twist, fold, cut, tear, stretch and stack 2DM on demand

(ii) completely removing ‘bubbles’ trapped between 2DM when multiple layers are
stacked on top of each other (similar to how air bubbles are trapped underneath
phone screen protector)

(iii) achieving a uniform, large area 2DM stacks (i.e., the surface should look exactly
same everywhere without any inhomogeneities or defects when multiple 2DM
are stacked on top of each other)
