Abstract

Significance Harnessing a material’s functionality in applications and for fundamental studies often requires direct manipulation of its crystal symmetry. We manipulate the crystal structure of Cu 2 S nanoparticles in a controlled and reversible fashion via variation of the electron dose rate, observed by transmission electron microscopy. Our control method is in contrast to conventional chemical doping, which is irreversible and often introduces unwanted lattice distortions. Our study sheds light on the much-debated question of whether a change in electronic structure can facilitate a change of crystal symmetry, or whether vice versa is always the case. We show that a minimal perturbation to the electronic degree of freedom can drive the structural phase transition in Cu 2 S, hence resolving this dilemma.
