The Big Bang frame of work for cosmology is a theoretical construct based upon one possible interpretation of the Hubble observation of the red shift from distant galaxiwa. Almost all of the scientific experimental evidence has been interpreted under the Big-Bang hypothesis. And the results have been very promising though with a few important drawbacks. The main point in our present work is to ...

We have examined steady-state and time-resolved luminescence properties of CdS:Te quantum dots (QDs). The transient emission spectra have a red shift along the emission process. Using singular value decomposition and multiexponential decay analysis, the luminescence is found to originate from two distinct and parallel channels: band-edge excitonic emission and trapping state emission. With incr...

We report on characterization of a set of AlGaN/GaN multiple-quantum-well (MQW) photodetectors. The model structure used in the calculation is the p–i–n heterojunction with 20 AlGaN/GaN MQW structures in i-region. The MQW structures have 2nm GaN quantum well width and 15nm AlxGa1 xN barrier width. The cutoff wavelength of the MQW photodetectors can be tuned by adjusting the well width and barri...

This paper established a physical axiom system. By the axiom system we can derive important physical laws such as momentum conservation law, Newton’s second law, Newton’s law of gravity, Schrödinger equation and Maxwell’s equations, simplified existing physical theories and explain some physical phenomenons those unresolved by traditional physical theories. We can also derive Schwarzschild solu...

We studied the spectral evolution of plasmon modes associated with silver nanotriangles as a function of dielectric overlayer thickness in the range of 5-300 nm. A substantial red-shift of the resonance is observed that oscillates with increasing over-layer thickness. We explain this previously unreported oscillation through the cavity quantum electrodynamical effect of the array of triangles c...
