Electronic materials are the type of materials which are typically used as core elements in a variety of device applications. These elements can be, for example, Laptops,Mouse,Keyboards,memories, displays, LEDs and could be easily seen in daily electronic gadgets such as mobile phones, computers, laptops, tablets, GPS devices, LED bulbs, TVs and monitors. Changing dimensions and level of functionality requires continuous efforts to develop state of the art materials to meet the technological challenges associated with development of these devices.All has been possible because of continuous efforts to improve fundamental understanding about the electronic properties of various materials and at various length scales as well as forms. Electronic properties of a material are governed by the response of electrons and other charged entities to external stimulus such as electrical potential difference and its variation, incident electromagnetic radiation, magnetic field, heat, mechanical forces etc. The field of Science and Technology of Electronic Materials involve understanding these correlations, as well as development of technologies for the synthesis/fabrication of materials with desired electronic properties.

Beginners can look at the following examples to appreciate the science of electronic materials: Example 1: Effect of differences in the arrangement of atoms (called crystal structure) for a particular element, in this case Carbon in diamond and graphite forms. Example 2: Effect of impurities on the electronic properties of a material

Example 3: Interfacing of two or more different materials with different electronic properties for desired device application.
