Universal phonon softening in the pseudogap state of TlBaCaCuO
Jia-Wei Hu, Kai Zhang, Yong-Chang Ma +5
Exploring the origin of the pseudogap is important for the understanding of superconductivity in cuprates. Here we report a systematical experimental study on the phonon vibrationa…
Order-disorder transition in -oligophenyls
Kai Zhang, Ren-Shu Wang, Xiao-Jia Chen
Poly(-phenylene) has been recognized as one important family of conducting polymers upon doping with donors or acceptors. This system possesses a chain-like structure with in…
Chain length effects of -oligophenyls with comparison of benzene by Raman scattering
Kai Zhang, Xiao-Jia Chen
Raman scattering measurements are performed on benzene and a number of -oligophenyls including biphenyl, -terphenyl, -quaterphenyl, -quinquephenyl, and -sexiphenyl a…
Observation of Meissner effect in potassium-doped -quaterphenyl
Jia-Feng Yan, Ren-Shu Wang, Kai Zhang +1
Inspired by the discovery of high temperature superconductivity in potassium-doped -terphenyl, we examine the possibility of superconductivity in -quaterphenyl with one more…
Superconductivity in potassium-doped 2,2-bipyridine
Kai Zhang, Ren-Shu Wang, An-Jun Qin +1
Organic compounds are always promising candidates of superconductors with high transition temperatures. We examine this proposal by choosing 2,2-bipyridine solely composed by C,…
