The atomic and electronic structure of positively charged P vacancies on InP(110) surfaces is determined by combining scanning tunneling microscopy, photoelectron spectroscopy, and density-functional theory calculations. The vacancy exhibits a nonsymmetric rebonded atomic configuration with a charge transfer level 0.75+/-0.1 eV above the valence band maximum. The scanning tunneling microscopy (...
In order to ensure that the tunnel deformation and surface settlement are controlled within allowable range during construction process, design unit has compiled technical measures monitoring schemes for ground control of this project. Based on example a shallow tunneling project Subway line 8, paper analyzes discusses method in detail puts forward corresponding control.
We investigate the nonlinearity-assisted quantum tunneling and formation of nonlinear collective excitations in a matter-wave interferometer, which is realised by the adiabatic transformation of a double-well potential into a single-well harmonic trap. In contrast to the linear quantum tunneling induced by the crossing (or avoided crossing) of neighbouring energy levels, the quantum tunneling b...
It is very important for controling ground deformation, ensuring safely operation and decreasing energy cost to perform harmoniously control of multi-system in shield tunneling. The decision suport system is proposed based on in-situ observed data in sheild tunneling. The soil charactiristics are identified according to in-situ observed data and fuzzy clustering model of soil layer classificati...
