2. Abstract
Quantum dot cellular automata a novel nanoscale technology for binary
logic synthesis. Transistorless nanocomputing device that has the lighting
speed.

3. Basic concept of logic synthesis

4. Single electron tunneling devices use this
approach
Island system
for “electron
trapping “

5. In QCA
Generally
used as ‘Si,
GaAs, InP,
InSb etc.”

6. Multilayer visualization in QCA design
Each layer of cells
invert the output
signal.
Standard separation
is (11.50nm).

7. XOR gate layout design in QCA
Introduction to partial
polarization

8. pNAND gate implementation using partial
polarization concept

9. Dimensional scaling of the pNAND gate

10. MUX design

11. MATHEMATICAL MODEL
OF THE QCA DEVICE

12. Wave nature electron model of QCA

13. Tunneling time of the electron

14. Wave equation for electron tunneling from one qdot to another
qot through tunnel barrier
This equation is called Master Power Equation
in QCA device
Wave
function
Total utilized power
by the electron
Inverse square of the
tunneling time (𝑡−2)

15. Tunneling rate Master Equation in wave nature of
electron

16. Power dissipation Master Equation in wave nature of
electron
