The underlying mechanism of the superconducting-to-insulator transition under an applied magnetic field has been a topic of debate for many years. Here, the authors investigate the superconductor-to-insulator transition in 2D films and investigate the nature of the transition as a function of sample dimensions and reveal the importance of the quantum-Griffiths singularity.
