Abstract:
There is disclosed a dielectric reflector for selective wavelength reflection which comprises an alternately deposited series of thin films of silicon and silicon dioxide layers respectively arranged in an alternating sequence of at least one layer of each type of material. This reflector is suitable for use on the reflecting electrode of a liquid crystal video display panel fabricated on a semiconductor substrate. The use of the dielectric reflector in place of other types of reflectors increases the available reflectivity and permits a preselected color or wavelength to be preferentially reflected. The polysilicon layer of the dielectric reflector is doped with p-type or n-type impurities such as boron or phosphorus to make this layer electrically conductive.
Its easy to put off saving for the future as you focus on more immediate needs, writes Craig Stephens for U.S. News and World Report. But its never too late to start saving for retirement. However, youll need a change of mentality to prioritize your long-term retirement needs over short-term w
