Is Spintronics the Future of the Electronics Industry?
Developing smaller, more efficient, and more powerful electronic devices has been the trend. However, as the size of the individual bits approaches atomic dimension, tunneling effects as well as heat-control are expected to cause major problems and essentially render the conventional use of electric charge in the digital logic all but useless. This basically suggests the existence of a fundamental limit in the miniaturization process if electric charge continues to be the centerpiece in the digital logic of these devices.
Instead of using the presence or absence of charge in the digital logic, Will we be looking at a future of positive and negative 1/2 spin as the core of digital logic? As a direct product of miniaturization, is spintronics the future of the electronics industry?
