Revolutionary P-BCN Prototype: A Breakthrough in Ternary Pentagonal Design


Figure: Penta-BCN

A recent study by researchers Shambhu Bhandari Sharma, Ramchandra Bhatta, Rajendra Adhikari, and Durga Paudya has revealed the intriguing properties of a new ternary pentagonal prototype called pentagonal boron nitrogen carbide (p-BCN). The study, which was performed using density functional theory (DFT) calculations, found that p-BCN is a mechanically, thermally, and dynamically stable direct bandgap semiconductor with excellent piezoelectric response. 

This new material, composed of B, N, and C atoms, has an almost equivalent atomic size and mass, making it lightweight and benign to the environment. The study found that p-BCN exhibits intrinsic polarization and piezoelectricity, as well as lattice thermal conductivity up to 97.49 at room temperature. Additionally, hydrogenation of the pristine p-BCN changes it from a direct bandgap of 1.70 eV to an indirect bandgap of 4.46 eV. The bandgap of hydrogenated p-BCN is tunable up to 3.26 eV under biaxial strain. 

The researchers found that p-BCN is an excellent optoelectronic material due to its favorable surface for photon-electron interaction. The study predicts that p-BCN has excellent optical response, including a good static dielectric constant and refractive index, strong optical absorption with small energy loss, and reflectance peaks in both visible and ultraviolet regions. The anisotropic geometry of p-BCN also leads to strong optical anisotropy behavior in the monolayer. While the study did not perform a meticulous analysis of the optoelectronic properties of p-BCN, the researchers believe that their findings on the exceptional physical and chemical properties exhibited by the p-BCN monolayer make it a proper candidate material for nanomechanical and optoelectronic device applications. In conclusion, the study highlights the potential of p-BCN as a stable direct bandgap semiconductor with excellent piezoelectric and optoelectric properties, making it a promising material for use in a variety of applications in the fields of nanomechanics and optoelectronics.

How to install siesta(DFT code) in ubuntu?

  Required libraries to download Siesta-4.1-b4.tar  (Try to download upgrade version) with some package ● lapack-3.8.0.tar.gz ● libgridxc-0.8.4.tar ● Xmlf90-1.5.4.tar.gz ● hdf5-1.8.21.tar.bz2 ● hdf5-1.10.4.tar.gz ● netcdf-c-4.6.1.tar.gz ● netcdf-c-4.6.2.tar.gz ● netcdf-fortran-4.4.4.tar.gz ● zlib-1.2.11.tar.gz Steps to install siesta ●First extract the siesta tar file. ●Then through the terminal go to Obj of siesta folder. (i.e$obj ) ● $sh ../Src/obj_setup.sh ● Type $cp gfortran.make arch.make ● Type ls, then we saw arch.make file inside obj folder of siesta. ● Finally, type $make Then we got siesta executable inside Obj folder which is ready to run. https://youtu.be/EI1vuPfeLPs

Empowering Women for a Sustainable Future “Climate Change in Nepal”

Climate change is one of the most significant challenges facing humanity today, with devastating impacts on people, animals, and the environment. Nepal is one of the most vulnerable countries to climate change, with the Himalayan region being particularly affected. In this context, it is crucial to understand the intersectionality of climate change with gender and its impact on the people of Nepal, especially women. Women in Nepal are often the most affected by the impacts of climate change, as they are disproportionately responsible for household and community-level tasks such as food and water collection, which are affected by climate change. Women are also more likely to live in poverty and have fewer resources and opportunities to adapt to the impacts of climate change. One of the most significant impacts of climate change on women in Nepal is related to agriculture. Women in Nepal are responsible for up to 80% of agricultural work, but their access to resources such as land, water...

New Study Reveals Clues Behind Twisted Graphene Superconductor

Scientists at The Ohio State University have produced new evidence of how graphene, when twisted to a precise angle, can become a superconductor. In a study published in the journal Nature, the team reported on their finding of the key role that quantum geometry plays in allowing this twisted graphene to become a superconductor. Graphene is a single layer of carbon atoms, and in 2018, scientists discovered that, under the right conditions, graphene could become a superconductor if one piece of graphene were laid on top of another piece and the layers were twisted to a specific angle. This creates twisted bilayer graphene. However, the conventional theory of superconductivity doesn't work in this situation. In a conventional metal, high-speed electrons are responsible for conductivity. But twisted bilayer graphene has a type of electronic structure known as a "flat band" in which the electrons move very slowly—in fact, at a speed that approaches zero if the angle is exactl...
