Linear scaling calculation of band edge states and doped semiconductors

open access: yes, 2006
Linear scaling methods provide total energy, but no energy levels and canonical wavefuctions. From the density matrix computed through the density matrix purification methods, we propose an order-N (O(N)) method for calculating both the energies and ...

Selective Sequestration of Toxic NOx Gases by P‐Doped Graphene: A Density Functional Theory Study

open access: yesAdvanced Physics Research, EarlyView.
P‐doped graphene (P‐grap) is explored as an NOx sensor through DFT simulations. The analysis of its geometry, binding energies, electronic properties, and atom‐in‐molecule characteristics demonstrates that P‐grap is a selective sensor for NOx among a mixture of various gases.

Synthesis of boron nitride nanotubes by boron ink annealing

open access: yesNanotechnology, 2010
Ball-milling and annealing is one effective method for the mass production of boron nitride nanotubes (BNNTs). We report that the method has been modified to a boron (B) ink annealing method. In this new process, the nanosize ball-milled B particles are mixed with metal nitrate in ethanol to form an ink-like solution, and then the ink is annealed in ...
