Description
Summary:A two-dimensional (2D) periodic array of gallium arsenide quantum dots, embedded on the surface of a resonant tunneling diode (RTD), is investigated as a system for image processing. The embedded dot structures have been developed as a high-speed parallel processing device. The image processing task by QDs can be done through the realization of QD Boolean logic gates. It is shown that if the image data are introduced as initial conditions to these QD logic gates, the response of the system realizes a morphological image processing task similar to image dilation and erosion.
