First-principles study on physical properties of a single ZnO monolayer with graphene-like structure
Z. C. Tu
The elastic, piezoelectric, electronic, and optical properties of a single ZnO monolayer (SZOML) with graphene-like structure are investigated from the first-principles calculation…
Elasticity and piezoelectricity of zinc oxide crystals, single layers, and possible single-walled nanotubes
Z. C. Tu, X. Hu
The elasticity and piezoelectricity of zinc oxide (ZnO) crystals and single layers are investigated from the first-principles calculations. It is found that a ZnO thin film less th…
Molecular Motor Constructed from a Double-Walled Carbon Nanotube Driven by Axially Varying Voltage
Z. C. Tu, X. Hu
A new molecular motor is conceptually constructed from a double-walled carbon nanotube (DWNT) consisting of a long inner single-walled carbon nanotube (SWNT) and a short outer SWNT…
Comment on "Highly Extended Image States around Nanotubes"
Z. C. Tu, Z. C. Ou-Yang
A Comment on the Letter by Granger et.al., Phys. Rev. Lett. 89, 135506 (2002).
Spiral symmetry and general Bloch's theorem
Z. C. Tu
In this paper, spiral symmetry in cylindrical coordinate and general Bloch's theorem induced from it are discussed. This general Bloch's theorem is useful for considering the prope…
Single- and multi-walled carbon nanotubes viewed as elastic tubes with Young's moduli dependent on layer number
Zhan-chun Tu, Zhong-can Ou-Yang
The complete energy expression of a deformed single-walled carbon nanotube (SWNT) is derived in the continuum limit from the local density approximation model proposed by Lenosky {…
