Scaling behaviors of critical current density $$J_{c}$$ in $$\hbox {MgB}_{2}$$ thin films are investigated on different films with thickness of 100 nm, in comparison with 50- and 10-nm films based on a comprehensive scaling formula. Experimental data

Scaling analyses are performed on the critical current density J c in MgB2/NbN/Si thin film. In our previous work on MgB2/SiC/Si film [Mat. Sci. Eng. 502 (2019) 012184], we have shown that J c data well scale on a single line with the reduced scaling
