Penta graphene is an allotrope of carbon composed of pentagons. It contains sp2 as well as sp3 hybridised carbons. Penta-graphene is a novel 2D material recently introduced in the graphene family with an intrinsic bandgap which makes it a promising candidate for electronic applications. Here, we present theoretical work on structural, electronic and thermal properties of pristine penta-graphene and doped penta-graphene system based on generalised gradient approximation in the framework of density functional theory. Whereas graphene is semi-metal pentagraphene behaves like insulator with large band-gap.The electronic and transport properties were computed and compared with related graphene properties. We also present a symmetry-based analysis of the energy band structure in order to explain the interesting properties of this system. Much of these study already exist, we have performed these calculations to get a feel for this 2D system. Further study, with more results are expected to be presented in the poster.
I would like thank High performance computing centre (HPCE) for the computational facility. I would like to thank my co-supervisor Dr.rer.nat Somnath Bhattacharyya for allowing me to use the lab facility and access to VASP code for carrying out this work. I would like to thank Dr. Sitansh Sharma for the fruitful discussions we have regarding this work.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
