Thin Films

Difference between bulk and polycrystalline films Advantages for each system Cost factor, Ease of preparation, environmental impact, Amounts of needed starting materials are much smaller in case of thin film technology Manufacturing: Substrates used (glass & Transparent Conducting Layers: Fluorine doped tin oxide and tin doped indium oxide) Simple methods Electrochemical depositions Chemical bath depositions

Fiber Optics

The lecture describes how fiber optics are used in modern communications. Basic principles are described. Components (receivers, channels, Multiplexers are described. How to convert an electric current into light and vice versa. State of the art The critical angle concept Core lines, coatings and cladding are described

Capacitions And Super Capacitions

The lecture described how supercapacitors function, Effect of high surface area and effect of the insulator layer with high dielectric material in between Flexible super-capacitors by using FTO on plastic sheets is described. Comparison with modern batteries is described, showing advantages of batteries and super-capacitors Applications in modern hybrid and electric cars are described.
