BNC nanoshells: a novel structure for atomic storage

Area of Science:

• Materials Science
• Condensed Matter Physics
• Computational Chemistry

Background:

• Nanomaterials, including graphene and boron nitride nanoribbons, are of significant interest due to their unique electronic and structural properties.
• The formation and stability of complex nanostructures from simpler precursors are crucial for developing novel materials.

Purpose of the Study:

• To investigate the structural and electronic properties of carbon, boron nitride (BN), and hybrid BNC nanoshells.
• To explore the potential of these nanoshells for applications such as molecular storage.

Main Methods:

• Utilizing Quantum Molecular Dynamics (QMD) and Density Functional Theory (DFT) for simulations.
• Analyzing the structural evolution and electronic band structures of the nanoshells.
• Investigating the effect of an applied transverse electric field on the nanoshell structure.

Main Results:

• Nanoribbons spontaneously collapse into stable nanoshell structures within femtoseconds.
• The resulting nanoshells can be metallic or semiconducting, depending on their stoichiometry.
• Spin splitting near the Fermi level is observed in pure carbon and hybrid BNC nanoshells.
• An applied electric field causes the nanoshells to open, indicating potential for molecular storage.

Conclusions:

• The study demonstrates the spontaneous formation of stable BNC, BN, and carbon nanoshells with tunable electronic properties.
• The observed response to electric fields suggests promising applications in molecular storage, exemplified by H2 molecule adsorption.
