Query: Probing the minigap in topological insulator-based Josephson junctions
  under radio frequency irradiation   Recently, a contact-resistance-measurement method was developed to detect the
minigap, hence the Andreev bound states (ABSs), in Josephson junctions
constructed on the surface of three-dimensional topological insulators (3D
TIs). In this work, we further generalize that method to the circumstance with
radio frequency (rf) irradiation. We find that with the increase of rf power,
the measured minigap becomes broadened and extends to higher energies, in a way
similar to the rf power dependence of the outer border of the Shapiro step
region. We show that the corresponding data of contact resistance under rf
irradiation can be well interpreted by using the resistively shunted Josephson
junction model (RSJ model) and the Blonder-Tinkham-Klapwijk (BTK) theory. Our
findings could be useful when using the contact-resistance-measurement method
to study the Majorana-related physics in topological insulator-based Josephson
junctions under rf irradiation.
