Research Highlights

  • Mohanta et al., whose article in Nanoscale, 2019,11, 21880-21890 has been specially selected to feature in an Editor’s Choice web collection focussing on computational nanomaterials research. It happens to be the first report on out-of-plane piezoelectricity (d33) in 2D van der Waals heterostructures. The experimental verification of this theoretical prediction, which followed subsequently, is truly rewarding!

  • DST acknowledged the work by Prof. Abir De Sarkar & his Ph.D. student, Manish Kumar Mohanta in their recent publications in Nanoscale and American Chemical Society have demonstrated induction of superhigh out-of-plane piezoelectricity via stacking one monolayer over the other in the 2D nanostructure.

    The induction of this phenomenon is based on two-dimensional van der Waals heterostructure (vdWH) comprising of 2D monolayers, the vdWH is a new approach in materials design where different monolayers having complimentary properties are combined together to surmount their intrinsic limitations. When two monolayers are stacked over one another to constitute a vdWH, various factors affect the electronic properties. The dipoles arising at the interface due to the large charge density difference between the two constituent monolayers extend out into the interlayer region, which result in such an ultrahigh value in out-of-plane piezoelectricity. In their work funded by the Department of Science and Technology under Nanomission and Council of Scientific and Industrial Research (CSIR), India the researchers have predicted that predicted that the the out-of-plane piezoelectric coefficient of the materials designed by them will reach as high as 40.33 pm/V, which is very high as compared to the bulk materials, such as wurzite AlN (5.1 pm/V), GaN (3.1 pm/V), commonly used in industry.

  • This work, performed by Mr. Manish Kumar Mohanta and Prof. Abir De Sarkar, introduces the HfN2 monolayer as an exceptionally promising valleytronic material having valley properties complementary to that of Group VI TMDC. This is a report on valley contrasting physics and valley spin splitting (VSS) at the conduction band (CB), which would strongly motivate experimentalists to synthesize and explore this predicted two-dimensional material.
