Transparent electronics by Jaya Simha Reddy

  1. 1. Presented by: Jaya Simha Reddy Nandyala 150040588, ECE
  2. 2. Transparent electronics is an emerging technology that employs wide band- gap semiconductors for the realization of invisible circuits.
  3. 3. Transparent mobile
  4. 4.  Structure of graphene They are so small that cannot be distinguished by eyes.
  5. 5. Transparent Battery "The clear flexible plastic in the image is a battery, which is just 1atom thick. The power rate performance is strikingly high it only takes one minute to fully charge the battery and it has a long cycle life, often exceeding 1,000 cycles."
  6. 6. Nontoxic elements and cheap materials Cheap processing and mass production Band gap energy with high mobility
  7. 7. Nontoxic elements and cheap materials Cheap processing and mass production Band gap energy with high mobility
  8. 8. Nontoxic elements and cheap materials Cheap processing and mass production Band gap energy with high mobility
  9. 9.  transparent USB memory drive:  Polytron Technologies has produced a transparent USB memory stick that will come in 8, 16 & 32GB options. The USB has an embedded LED so that you know that it is connected and working.
  10. 10.  ITO: Indium $92/kg(2002) $930/kg(2013) Can only satisfy the demand till 2028 (Source: American Mining Association 2013) Indium is toxic!  • Graphene: Carbon. Can be found everywhere, very cheap, non-Toxic.
  11. 11. ITO is a ceramic material, poor flexibility
  12. 12. Chinese ITO production: Chinese ITO demand: Other country’s ITO demand: Other country’s ITO production:
  13. 13.  Intensive effort to find the best material for the channel (semiconductor) in TTFTs. Aligned Nanotubes
  14. 14. Key features: 1. Low T 2. Keeping alignment 3. Repeatable 4. Scalable @ 5. compatible with graphene
  15. 15.  •Chemical Vapor Deposition (CVD)  •arc discharge  •laser ablation  •HIPCO®: Hi-pressure carbon monoxide  •surface mediated growth of vertically-aligned tubes by Plasma Enhanced Chemical Vapor Deposition (PECVD)
  16. 16. Aligned CNTs Graphene
  17. 17.  TRRAM device is based on an capacitor structure which provides a transmittance of 81% in the visible region of the chip. the data retention is expected to be about 10 years.
  18. 18. R & D:  IPR for : Graphene, Aligned CNTs  Material improvement  Applications  Trolls & Attorneys  Concept Design  Circuit Design  Product Design Material provider:  Graphene  Aligned CNTs
  19. 19. Component Maker: Transparent circuit Transparent display panel Heated Glass Transparent RAM Transparent Electric Storage Transparent Battery …other transparent component
  20. 20. Application service provider: Operating System Software Applications Retailer: Dept Store Direct Catalogue Distributors E commerce Mass Merchants National Chain Consumer
  21. 21. Recycling: Collection Refurbishment Dismantling Recycling Components Recycling Materials Bio-decay
