Current methods does not allow for an industrially feasible production of 2D-layered bulk copper sulfide. Such material can be used as is or be exfoliated into monolayers to exhibit significant, advantageous commercial characteristics for specific technological applications.
Our cutting-edge invention provides a simple and scalable method for the synthesis of single stoichiometry 2D layered bulk copper sulfide, which does not require nor produce toxic compounds.
The Commercial Benefit
This invention presents significant commercial benefits. Our 2D layered material:
• The synthesis yields bulk quantities and not emit toxic gases from the reaction to the environment.
• Provides a method for depositing monolayers on a substrate by sonication and dropcasting (top-down method).
• Provides a new p-type 2D layered material, which is a critical building-block for the fabrication of devices such p-n junctions, heterojunctions, and complementary metal-oxide-semiconductor (CMOS) field effect transistors.
This is a new material which exhibits specific properties such as:
- 2D layered; can be exfoliated into monolayers
- high electrical conductivity
- p-type with bandgap of 2.5 eV
These properties make this material appealing for applications in electronic devices, thermoelectrics, and energy storage
• Target Makets/Industries • Battery electrodes (material as is or as additive)
• Monolayers or few layers for heterojunctions
• Additive for fabrication of solar cells
