Lecture5 Types of Semiconductor junctions ALL PV cells comprise of junctions between different materials of different doping pn homojunction fabricated in the same semiconductor material such as cSi . 8 Other Unipolar Junctions The metal semiconductor junction is the most studied unipolar junction be not the only one that occurs in semiconductor devices Two other unipolar junctions are the homojunction and the H . by Dr. . Vani. Gupta . . Definition and Classification of cell junction. Cell junction is the connection between the neighbouring cells or the contact between the cell and extracellular matrix.. O. f Presentation. Gunn Diode. Gunn Diode. . Definition. History. Construction . . . Definition:. S. uch type of semiconductor. device which have only N type doped. (semiconductor) material, is called “Gunn Diode.”. CELL JUNCTIONS. In certain tissues the membranes of adjacent cells may join and form a junction called a cell junction.. These are specialized areas of the cell membrane that provide contact between the cells.. Semiconductors. A Semiconductor. is a material whose resistivity is between that of a good conductor and a good insulator. .. Examples of materials which are semiconductors are Silicon and Germanium.. 2012.

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-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..
