SPINTRONICS: AN INTRODUCTION INTRODUCTION: From the earliest transistor to the remarkably powerful microprocessers‚ most electronic devices have employed circuits that express data as binary digits‚ or bits: ones and zeroes represented by the existence or absence of electric charge. Furthermore‚ the communication between microelectronic devices occursby the binary flow of electric charges.The technologies that emerged from this simple logic have created a multitrillion dollar per

GIANT MAGNETORESISTANCE In this essay we will explore some brief historical information about Giant Magnetoresistance (GMR)‚ its basic principle of operation and some of its current and potential applications. To begin with‚ the idea of GMR is based on the change in the resistance of very thin (scale of nanometers) ferromagnetic materials when an external magnetic field is applied. The term “Giant” is to describe the size of the change in the resistivity in the order of 10% to 20%‚ considered to

Spintronics devices: Spintronics are mostly used in storage and memory devices. They have the capability of storing huge quantity of information and can be used as a storage device like hard disk and so on. The procedure employed by the spintronics devices to store data are systematic and structured. Originally‚ the spin of the electron is utilized to accumulate and write the data in a specific direction (spin “upward” or spin “downward”). Then‚ the spin of other left out moving electron particles

Green Computing: Should It Be Photonics or Spintronics for Quantum Computers? Xavier Mattam xaviermattam@hotmail.com Abstract - Quantum Computers are widely acclaimed as the future computers. There is so much research being done in this field of Quantum Computers that one would rightly feel that the advent of Quantum Computers for everyday use is not far off. But at a time when Global Warming has become a real threat to our very existence‚ the question we need to responsibly ask ourselves before

Abstract: Nanoelectronics refer to the use of nanotechnology on electronic components‚ especially transistors. Although the term nanotechnology is generally defined as utilizing technology less than 100nm in size‚ nanoelectronics often refer to transistor devices that are so small that inter-atomic interactions and quantum mechanical properties need to be studied extensively. As a result‚ present transistors (such as CMOS90 from TSMC or Pentium 4 Processors from Intel) do not fall under this category

Zinc oxide in a mixture with a about 0.5% iron(III) oxide (Fe2O3) is called calamine and is used in calamine lotion. There are also two minerals‚ smithsonite and hemimorphite‚ which have been called calamine historically (see: calamine (mineral). Zinc peroxide‚ ZnO2 .½ H2O‚ is a white to yellow powder that is used in antiseptic ointments. Zinc white is used as a pigment in paints and is more opaque than lithopone‚ but less opaque than titanium dioxide. It is also used in coatings for paper
