Hidden phase in a two-dimensional Sn layer stabilized by modulation hole doping

Hidden phase in a two-dimensional Sn layer stabilized by modulation hole doping

Broken symmetry phases may occur in 2D materials upon doping, yet introducing doping without inducing chemical disorder remains a challenge. Here, the authors use a modulation doping approach that unveils a hidden equilibrium phase involving spontaneous symmetry breaking in a hole-doped Sn bilayer.
