In contrast, exploiting the layered traingular network of the delafossite structure, the QUESTDO project aims to establish delafossite oxides as a completely novel class of interacting electron system with properties and potential not known in more established systems.
Delafossite CuBO2 powder was prepared by solid state reaction for phase transition and sintered at low temperature range of 100-400 oC.
As CuBO2 delafossite is a transparent conducting oxide with a wide bandgap and may have potential applications as transparent electrodes and in other opto-electronic devices.
