Structure Property Relationships of the Exotic Insulator-Insulator Transition in CeMnAsO1- x F x : A Potential Excitonic Insulator
{{output}}
A novel quantum insulator-insulator transition was recently reported upon F- doping the Mott insulator CeMnAsO1-x F x . Below the transition, the resistivity increases by more than 2 orders of magnitude over a narrow temperature range, and a colossal Seebeck e... ...
