Observation of the linear stark effect in a single acceptor in Si.

چکیده
The Stark splitting of a single fourfold degenerate impurity located within the built-in potential of a metal-semiconductor contact is investigated using low temperature transport measurements. A model is developed and used to analyze transport as a function of temperature, bias voltage, and magnetic field. Our data is consistent with a boron impurity. We report g factors of g_{1/2}=1.14 and g_{3/2}=1.72 and a linear Stark splitting 2Delta of 0.1 meV.

Effect of local strain on single acceptors in Si
We explore the low temperature transport through a resonant acceptor impurity located near a metalsemiconductor interface and observe a large shift 12 meV and splitting 0.8 meV of its ground state. The shift is attributed to the quadratic Stark effect resulting from the electric field of the electrostatic barrier. The splitting is too large to be attributed to a linear Stark splitting. We calcu...
متن کاملStudy of the Mechanism and Causes of Pore Formation in Sr-modified Al-Si Alloys
The formation of microporosity in modified Al-Si alloys has been reviewed in the present study. A major concern in modification is the increased tendency to form microporosity in the macro-shrinkage free Al-Si alloy castings. It has also been demonstrated that at low hydrogen contents (0.1cc/ 100g, Al), where only shrinkage porosity should occur, the effect of Sr-modification on porosity conten...
متن کاملEffects of on-center impurity on energy levels of low-lying states in concentric double quantum rings
In this paper, the electronic eigenstates and energy spectra of single and two-interacting electrons confined in a concentric double quantum rings with a perpendicular magnetic field in the presence of on-center donor and acceptor impurities are calculated using the exact diagonalization method. For a single electron case, the binding energy of on-center donor and acceptor impurities ar...

Background and purpose: In MRI the concentration of contrast agent is indirectly measured from signal intensity (SI). It is important to find the maximum linear relationship between SI and concentration of the iron oxide nanoparticles for perfusion measurement. The aim of this study was to investigate the effect of inversion time on SI and the maximum linear relationship between SI and concentr...

Discharge of contaminants in the acceptor ambient has negative environmental impacts. Extremely shallow acceptor ambient conditions will have a significant impact on the diffusion of the contaminants flow. To achieve the effect of the hydraulic, geometric and environmental conditions of the contaminant flow in the acceptor ambient, an experimental model of surface draining was applied. The mode...
