Comment on “Tunneling-tip-induced collapse of the charge gap in the excitonic insulator Ta2NiSe5”
In this study, we investigate the discrepancy between the estimate of Q. He et al. [Phys. Rev. Res. 3, L032074 (2021)], who observed a remarkable collapse of the exciton gap in Ta2NiSe5 due to the electrostatic field between the scanning ...
