Optoelectronic characterization of organic photodiodes, light sources and photoluminescent emitters

Abstract

In the last century, wireless communication has been the fastest growing segment of the communications industry. In 1864 James Clerk Maxwell showed mathematically that electromagnetic waves could propagate through free space. However, the existence of electromagnetic waves was experimentally demonstrated by Heinrich Rudolph Hertz in 1888. It was in 1895, Sir Jagadish Chandra Bose demonstrated the first wireless communication using electromagnetic waves to ring a bell remotely by using gunpowder9. Since then, wireless communication technology has had many major pathbreaking developments starting from the invention of telegraphy and radio to the invention cellular mobile technology. Wireless technology systeM.S. have experienced exponential growth over the last decade and there are currently around two billion users worldwide. Due to this, the available radio spectrum below 10 GHz has become insufficient to all the users worldwide. This has sparked a need for the use of the radio spectrum above 10 GHz10.
