Item no.: C04 Description A perovskite is any material with the same type of crystal structure as calcium titanium oxide (CaTiO3), known as the perovskite structure, or XIIA2+VIB4+X2−3 with the oxygen in the face centers. Perovskites take their name from the mineral, which was first discovered in the Ural mountains of Russia by Gustav Rose in 1839 and is named after Russian mineralogist L. A. Perovski (1792–1856). The ideal cubic-symmetry structure has the B cation in

Electron circle are made in metal coil and the diameters are 210mm and 145mm.
Item no.: F22 Introduction Rather than the energy continuity considered in classic physics, the energy level of a photon or an electron, viewed from quantum theory, exhibits an integer multiple of hf (here h is planks constant and symbol of f indicates the frequency of light wave). That means a light is emitted from or
Item no.: F23 Introduction In general, light spectrum could be classified into discrete spectrum and continuous spectrum. However, both absorption and emission are the main typical pattern for discrete spectrum. Unlike the discrete way mentioned above, typical continuous spectrum, in this experiment, will be investigated. Here a slice with 500line / mm grate will be
Item no.: F19 RLC circuit has a very important feature, that is, the produced amplitudes of circuit-current will closely depend on the input frequency. Generally speaking, partial signal will be filtered, but partial might be augmented as several power sources with different frequency, in the circuit, are delivered simultaneously. Here amplified signal of frequency is
Item no.: F18 Introduction In1820, an electromagnetic theory was initiated by Oersted. Here the physical experiment relative to magnetic field induced by a current-carry wire was proposed. During 1820~1827, the theoretic model was further quantified by Ampere’s. In 1831, the so called Faraday’s law amounted the current induced along the closed loop while a time
