The researchers developed unique ultra-thin cobalt ferrite nanosheets with Curie temperature of over 390 K that makes them suitable for use in making a room-temperature magnetic semiconductor
Two-dimensional ferromagnetic materials exhibit intrinsic magnetic states that are stable at or above ambient temperature which provides practical semiconductor systems. The enhancement of 2D magnetic semiconductors for applications in unique room-temperature would develop the current 2D material choices and significantly broaden their application potential. Since only a few studies exist on developing a 2D magnetic semiconductor with Curie temperatures greater than ambient temperature. The researchers developed cobalt ferrite nanosheets that display exceptional semiconducting characteristics and consist of strong switchable activity, these features make them suitable for application in fabricating a room-temperature magnetic semiconductor. This research provides a route for new possibilities such as electromagnetic sensing and data storage.
The two-dimensional (2D) materials provide unique features with remarkable efficiency and extremely thin thickness that can span practically all electrical phases and functions in crystalline materials. Cobalt ferrite nanosheets are developed by researchers with one unit cell size and implemented the stable-confined van der Waals deposition technique. This results in a unique blend of room-temperature ferromagnetism characteristics for a magnetic semiconductor. The 2D magnetic order is linked with the substantial inherent spin fluctuations that can be traced in atomic scale thin layers of several 2D materials.
This recent study published in the journal Nature Communications sheds light on the fabrication of air-stable semiconductive cobalt ferrite nanosheets with thicknesses as low as one unit cell through a simple chemical vapor deposition (CVD) technique. The development of a unique room-temperature 2D magnetic semiconductor will enhance the current 2D material choices and would in turn broaden their application potential.
