Simulation of Imperfection on Image-Charge Quantum Cellular Automaton Using Image Charge Effect

Abstract
The influence of the imperfection of distribution of quantum dots on the behavior of QCA devices using image charge effect is investigated.The quantum dots of the cells of QCA are strictly confined on the four corners of a square cell.When considering the existing technology of manufacture of quantum dots,imperfection is unavoidable.We simulate the situation when the imperfection of the distribution of quantum dots is normal distribution.Also,we estimate the temperature on which the QCA can work correctly.The result indicates that the QCA can work properly when the error is less than 0.1.Meanwhile,if the size of the cells is decreased,the QCA can work above room temperature.-
