DESCRIPTION: will introduce a possible universal exfoliation m
 echanism for massive\nproduction of 2D materials f
 rom their bulk counterparts. Using first\nprincipl
 es calculations\, we demonstrate that spontaneous 
 exfoliation can\nbe induced by introducing holes i
 n layered materials. In contrast to the\nintroduct
 ion of exccess electrons and electron-hole pairs\,
  creating hole\nstates weakens the interlayer inte
 ractions\, leading to layer separation.\nOur resul
 ts may provide a universal route for producing lar
 ge-area\nmonolayers by controlling their hole conc
 entrations.
