Point-contact tunneling spectroscopy measurement of Cu${}_x$TiSe${}_2$: disorder-enhanced Coulomb effects

Katherine Luna, Phillip M. Wu, Justin S. Chen +2

We performed point-contact spectroscopy tunneling measurements on Cu${}_x$TiSe${}_2$ bulk with $x=0.02$ and $0.06$ at temperatures ranging from $T=4-40$ K and observe a suppression in…
