Session J1 - Poster Session II.
POSTER session, Tuesday afternoon, March 04
Room Exhibit Hall 2/3, Austin Convention Center
A theoretical study of quasi-adiabatic clocking in quantum-dot cellular automata (QCA) will be presented. Quasi-adiabatic clocking is investigated by potential modulation of inter-dot barriers in order to keep the cells of a QCA near the ground state throughout the entire switching process. The electron tunneling is controlled by raising and lowering a potential barrier in the cell. Time-dependent electric field is calculated for various arrangements of line charged rods. The electric field intensity at a particular position and time is a representation of the barrier height in the cell.
