The Research Of Novel Simulation Method Of Single Electron Transistor Based On Master Equation And The Theory Of Single Electron Electronic Circuit

Along with silicon ULSI technology has seen an exponential improvement in virtually any figure of merit,as described by Moore's Law; the miniaturization of circuit elements down to the nanometer scale has resulted in structures which exhibt novel physical effects due to the emerging quantum mechanical nature of the electrons, the new devices take advantage of quantum mechanical phenomena that emerge on the nanometer scale ,including the discreteness of electrons.laws of quantum mechanics and the limitations of fabrication may soon prevent further reduction in the size of today's conventional field effect transistors(FET's). The paper are investigating several alternatives for example Quantum dot cellular automata and single electron transistor to substitute conventional field effect transistors(FET's) for ultra large scale integrated circuit;and I take research on the modeling of single electron transistor and single electron cicuit.First,The paper researchs the SPICE simulation of single electron transistor based on curve approach and Quasi-Analytical Model of single electron transisor,and simulate characteristic of single electon transistor with MATLAB tool.Secondly,the paper combine SPICE simulation program with master equation of single electron transistor, put forward novel SPICE simulation method of single electron transistor based on master equation, by choose master state of single electron transistor and build master equation of single electron transistor, afterward gain nonlinear cortrolled source of SPICE model of single electron transistor by solve the master equation of single electron transistor and simulate V-I characteristic of single electon transistor by SPICE program,it's result prove the method is availability precision comparing with master equation method. Thirdly,The paper researchs the application of single electron transistor and the synthesis theory of cicuit based on quantum dot cellular automata by synthesis example of Quantum cellular neural network based on build Schr?dinger equation of coupling quantum dot.At last,the paper researchs Digital Integrated circuit Design based on quantum dot cellular automata and design a 8-bit Quantum dot cellular adder by QCADsign based on A Method of Majority Logic Reducetion for Quantum Cellular Automata,it prove this designer of 8-bit Quantum dot cellular adder is correctly.
