Exfoliated Thin Crystals: A New Platform For Exploring Cuprate Physics

ORAL

Abstract

Electrostatic doping is a promising method for separating the effects of carrier density and disorder in the cuprates. To this end, we have produced exfoliated micro-samples of underdoped Bi-2212 on SiO2/Si substrates. Using this method we reliably produce crystals on the order of hundreds of square microns and as thin as a few unit cells. We present the results of extensive atomic force, optical and polarized Raman microscopy studies of these samples. Taken together these results clearly demonstrate these thin crystals have the same properties as bulk Bi-2212.
