Controlled suppression of the field-induced Bose metallic state via disorder tuning in a two-dimensional superconducting system

We investigate field-induced quantum phase transitions in a superconducting Ta thin film with a series of periodic hole arrays. While it is known that introducing a hole array can influence quantum phase transitions, this effect has not been systematically explored. Exploiting the effect of disorder in our platform, we discover remarkable suppression of the superconducting transition temperature and the Bose metallic state with increasing areal hole density. This systematic study on unique disorder indicates that the Bose metallic state can be reduced by the regulation of vortex motion.
