RELATIVISTIC CHIPS: THE SPINTRONICS THEORY
[attachment=43680]
INTRODUCTION
No microprocessor of the world can challenge BRAIN, the ultimate biochemical machine.
Moore’s law still holds good.
Heat and energy are the two main constraints of the present IC technology.
Relativity may be the Answer.
Even the world’s fastest computers are not very faster, but the electrons in them do.
RELATIVISTIC CHIPS:THE CONCEPT
Einstein proposed the THEORY OF RELATIVITY.
THOERY OF RELATIVITY suggests a new design for microchips that relies on the spin of electrons.
These so-called relativistic effects are all minuscule, however, unless the object accelerates to a significant fraction of c, which is about 300 million meters per second.
Though the high end chips are not as fast as light but the electrons inside them do.
SPINTRONICS:THE TECHNOLOGY
SPINTRONICS, short for spin electronics, is the study of electron spin in materials in order to better understand its behavior, with the hope of developing an entirely new generation of microelectronic devices.
RELATIVISTIC TRANSISTORS
SPIN FET was proposed in 1990 by Supriyo Datta and Biswajit A. Das, at Purdue University, in West Lafayette.
They proposed a current modulator device based on the electric field modification of spin precession in a narrow gap semiconductor. In this device, the spin-polarized electrons would be injected with the use of a ferromagnetic electrode that forms an ohmic contact with the semiconductor and would be detected with a second ferromagnetic electrode (spin analyzer) contact.
