    Abstract: According to classical physics theories, a moving particle cannot move to an environment with greater potential energy than its total energy during movement. But according to quantum theories, this event is known to be. This event is called tunneling. Tunneling is a probability, and it is measured by a transition coefficient. Correct calculation of...

    Abstract: In this work, the optical properties (absorption, absorption coefficient, refractive index, band- gap energy, extension coefficient, and reflection) of the five samples of isonitrosoacetophenone (C8H7NO2) was studied using Uv-Vis spectroscopy. The C8H7NO2 was dissolved in different amounts of (0.5, 1, 1.5, and 2) ml of distilled water. The effect o... Show More

    Abstract: Thin films of copper zinc tin sulphide (CZTS) have been deposited on glass substrate at various solution concentration and angular speed using sol-gel spin coating technique. Surface morphology showed that the deposited layers are continuous and pinhole free. The film’s particles are evenly distributed and adhered firmly to the substrates. X-ray di... Show More
