Anisotropic Resistance and Slow Time Scale Physics in Pt-Doped 1T-TiSe2

ORAL

Abstract

Electronic correlations can give rise to variety of insulating phases, ranging from Mott insulators [1] to spontaneously symmetry broken ground states [2]. Recently, Pt-doped 1T-TiSe2 has been shown to produce a new phase, interpreted previously in the context of the formation of an array of highly interacting one dimensional channels at sufficiently low temperatures [3]. Here, we present angle-dependent transport measurements on few-layer Pt-doped 1T-TiSe2 at 5% Pt doping. A strongly anisotropic in-plane resistance is observed which can be tuned by up to 2 orders of magnitude below the charge density wave transition temperature Tcdw ~ 200K. At the same time, the development of a nontrivial phase response of the electrons at ultralow frequencies on the order of 10Hz is observed. Our results are discussed in the context of an anisotropically pinned charge density wave, and possible connections to the previously reported model of one dimensional channels are made.
