GALLIUM PHOSPIDE: It has band gap of 2.3ev. it can be used for light emitting diodes which can emit green or red light. The red light is obtained with zinc or cadmium oxide doping.
SELENIUM: It is found in crystalline and non-crystalline form. It is used as rectifier material for photo voltaic cells and for xerographic printing. Selenium films are used as photo electric light meters. Its melting point is 2200C.
LEAD: it is soft heavy and bluish gray metal. It is highly resistant to many chemical actions but can corrode by nitric acid, lime and rotten organic substances. Lead and its compounds are toxic. It is mechanically weak it cannot withstand vibrations at high temperatures. It alloys easily with Tin and zinc and forms many commercial alloys, including solders and bearing metals.
It's working is based on the detail that if a beam of electron is subjected to the crossed electric field and magnetic field , it experiences a force because of each field. In ca
Rutherford's alpha-scattering experiment recognized that the mass of atom is concentrated with small positively charged region at the centre which is known as 'nucleus'. Nuclei
A small spool and a large spool Using nails for axles fasten a large spool and a smaller spool to a block of wood. Slip a rubber band in excess of both spools. Turn the larger
Energy gap: 2.4ev. The colour of pure cadmium sulphide is pale yellow. It melts only under at high temperature. It can be prepared in the resistivity range from 10 to
Dalton's law of partial pressures (J. Dalton) The overall pressure of a mixture of ideal gases is equivalent to the total of the partial pressures of its components; i.e., the
infrigious system capacity of spherical conductor is equal to ...........
The potential difference created across the P-N junction due to the diffusion of electron and holes is called potential barrier. For and for silicon On the average the
Agriculture: 1. Radio isotopes are used to verify the optimum amount of fertilizer for the plants. 2. It is used to kill bacteria and conserved food stuff. 3. It is used
Light propagates as transverse EM rays. The magnitude of electric field is much larger as compared to magnitude of magnetic field. We generally prefer to define light as electric f
