Transparent electronics
[attachment=68516]
INTRODUCTION
Transparent electronics is an emerging science and technology field focused on producing ‘invisible’ electronic circuitary and opto electronic devices, include consumer electronics, new energy sources, and transportation; for example, automobile windshields could transmit visual information to the driver.
COMBINING OPTICAL TRANSPARENCY WITH ELECTRICAL CONDUCTIVITY
Transparent conductors are neither 100% optically transparent nor metallically conductive. From the band structure point of view, the combination of the two properties in the same material is contradictory:
A transparent material is an insulator which possesses completely filled valence and empty conduction bands
Transparent electronics devices
To produce a transparent-electronics-based system, appropriate materials must be selected, synthesized, processed, and integrated together in order to fabricate a variety of different types of devices.
These devices must be chosen, designed, fabricated, and interconnected in order to construct circuits.
Each of which has to be designed, simulated, and built in such a way that they appropriately function when combined together with other circuit and ancillary non-circuit subsystems
CAPACITOR
An ideal capacitor is an electric field energy storage device possessing linear current-voltage derivative (i-dv/dt) characteristics.
. In order for this device to be completely transparent, all of the layers should be transparent
A thin insulator with a high dielectric constant (sometimes referred to as a ‘high-k dielectric, where ‘k’ denotes the relative dielectric constant) is best
