Is the Internet a good venue for getting online leads and sales? Oftentimes, online merchants are disappointed or disheartened and end up reverting to traditional media for their advertising needs. Creating a website is not enough. Submitting the URL (with appropriate Meta tags and keywords to make the site searchable) is not enough. Having a merchant account on your site is not enough. The best way to get the most traffic to go to your site is through the forging of relationships with other companies. Short of pounding the pavement or writing emails to anonymous companies who may not give you the time of day, the best solution offered by the internet today are Dhal . gaya. . suraj. . shamma. . jali.

Three important phenomena occurs during formation of . pn. junction: Diffusion, Formation of Space charge and Drift.. Movement of electrons from n-side to p-side (n>p) and the movement of holes from p-side to n-side is called (p>n) “. Mobility is a measure of the ability of an electron or a hole to get around inside a semiconductor. Scattering events lower mobility. As the temperature of a semiconductor increases, there will be more and more lattice vibrations.. Lecture-27. Photo-Catalysis. Acceleration of a photoreaction in the presence of a catalyst. . Photon is absorbed by an adsorbed substrate. . Photocatalytic activity (PCA) depends on the ability of the catalyst to create electron–hole pairs.. Lecture-7. External solar cell parameters.

Presented By Prof. D. M. Parshuramkar. N-Type Material. N-Type Material:. When extra valence electrons are introduced into a material such as silicon an n-type material is produced. The extra valence electrons are introduced by putting impurities or . Zero Biased Junction Diode. When . a diode is connected in a . Zero Bias. condition, no external potential energy is applied to the PN junction. However, if the diodes terminals are shorted together, a few holes (majority carriers) in the P-type material with enough energy to overcome the potential barrier will move across the junction against this barrier potential. This is known as the . Lecture-2. This Photo. by Unknown Author is licensed under . CC BY. — . 2. What is Optical Absorption?. Definition : This is the phenomena when any material object takes up the light energy (photon) and alters electromagnetic energy into heat energy of the absorber..
