a–d Drag resistance \({R}_{{{{\rm{D}}}}}^{{{{\rm{MG}}}}}\) as a function of Vint and VBG measured at four different temperatures: 200, 150, 50, and 1.5 K. The black solid/dashed lines in (a–d) depict the charge neutrality lines of the G/MG layers. The black circles in (c, d) mark the two cross points between the two SNPs of the MG layer and the CNP of the G layer. e–h \({R}_{{{{\rm{D}}}}}^{{{{\rm{MG}}}}}\) as a function of Vint for VBG = 0 V measured at four different temperatures. Inset in e: schematic of the drag setup. The arrows in (f–h) indicate the locations of SNPs and QNPs of the MG layer. Insets in (g, h): zoom-in views of \({R}_{{{{\rm{D}}}}}^{{{{\rm{MG}}}}}\) vs. Vint curves near the QNPs.
