Abstract In this paper, we engineered the physical properties of the isolated single-walled SiC nanotube (NT) such as (7,7). Through bundling the nanotube to tetragonal crystalline structure or creating the inherent point defects of both Si and C, the physical properties of the isolated single-walled SiC nanotube (7,7) will change notably. In use of the data calculated from the density functional theory using the Quantum SPRESSO Software, we studied the physical properties including the lattice constants, stability, band gap and the direction of translation point, charge density, bulk modulus, magnetization, symmetry number, radial buckling, effective mass and the velocity of carriers. All the data were compared with the pure isolated single-walled SiC nanotube.
