Nanomaterials

1. INTRODUCTION TO NANOMATERIALS Nanomaterials : At least one dimension within the nanoscale range, typically between 1 and 100 nm. These materials exhibit their unique properties due to their small size and high surface area-to-volume ratio. Nanomaterials :Nanoparticles, Nanotubes, Nanowires, Thin films etc. Applications :Electronics, medicine, energy and environmental science. Due to their novel properties nanomaterials have the potential to revolutionize many industries and technologies. 1

3. OPTO-ELECTRONICS Opto-electronics : Deals with electronic devices and systems that acts as source, detect, and control light. Mainly convert electrical signal to optical & vice versa. Opto-electronics Devices: LEDs, Solar cells, Optical fibers, and Laser systems. Field of Applications: Telecommunications, Data storage, and medical equipment to consumer electronics, aerospace and defense. Its impact on modern technology is vast and continues to grow. Optoelectronics is a growing field with ongoing research. LED SOLAR CELL LASER OPTICAL FIBRE References:- GeeksforGeeks , ResearchGate, FST Freiberg 3

4. SILICON IN OPTO-ELECTRONICS MICROPHOTONICS SILICON PHOTONICS Why Si???? Si is widely used in the field of opto-electronics, particularly in the study of silicon photonics. Electrical conductivity lies between conductor and insulator Formation of high quality insulating oxide layers: important in integrated circuit fabrication. It has the potential to enable fast data transfer, increase bandwidth capacity and reduce power consumption in various applications. References:- GeeksforGeeks , ResearchGate 4
