According to a research:

• According to the research results  the multicomponent, multilayered composite material device is called a van der Waals Schottky diode.
• It converts heat into electricity up to three times more efficiently than silicon a semi-conductor material.
• In addition,widely used in the electronics industry.

According to physicist:

• The ability of our diode to convert heat into electricity is very large compared to other bulk materials currently used in electronics.
• In the future, one layer could be attached to something hot.
• Like a car exhaust or a computer motor and another to a surface at room temperature.
• The diode would then use the heat differential between the two surfaces.
• To create an electric current that could be stored in a battery and used when needed.”
• In the world of electronics, Schottky diodes are used to guide electricity in a specific direction.
• They are made by attaching a conductor metal like aluminium to a semi-conductor material like silicon.This lowers resistance to the flow of electricity, making the device much more energy efficient.
