The comparative study of epitaxial 380-nm-thick p-Al0.091 Ga0.909 N materials without and with special surface chemical treatment is systematically carried out.
A new double-layer grating template is designed to reduce the out-of-band loss as much as 1.8dB when the loss of LP03 reaches 10.2 dB. Meanwhile, we propose a m
First-principles simulation is used to investigate the structural and mechanical properties of vacancy defective single-walled (5,5) carbon nanotubes. The relat
The angular distributions of elastic scattering for the 6Li +208Pb system have been measured at several energies around the Coulomb barrier. The parameters of o
The SOS (save our soul) response induced by DNA damage in bacteria E coli has raised a great interests in biophysics and has been extensively studied. Previousl
We investigate the shape-preserving propagation of N optical pulses in an (N + 1)-level medium. We solve Maxwell-Schrodinger equations exactly and provide sever
