Researchers at Oregon State University have solved a quest in fundamental material science that has eluded scientists since the 1960s, and could form the basis of a new approach to electronics. The discovery, just reported online in the professional journal Advanced Materials, outlines the creation for the first time of a high-performance "metal-insulator-metal" diode. "Researchers have been trying to do this for decades, until now without success," said Douglas Keszler, a distinguished...

Characterizing photoelectrons with quantum point contacts At the heart of the method is a so-called quantum point contact (QPC). This is a narrow conductive channel in a semiconductor circuit. The scientists created a 70-nanometer narrow channel, about as wide as the wavelength of electrons in the semiconductor. The key is that only one electron at a time will fit through the channel, making possible extremely high-precision measurements of the electric current. As described in the current...

Rice researchers introduce graphene-based amplifiers Rice University research that capitalizes on the wide-ranging capabilities of graphene could lead to circuit applications that are far more compact and versatile than what is now feasible with silicon-based technologies. Triple-mode, single-transistor amplifiers based on graphene -- the one-atom-thick form of carbon that recently won its discoverers a Nobel Prize -- could become key components in future electronic circuits. The discovery by...

Graphene, a one-atom-thick layer of graphitic carbon, has great potential to make electronic devices such as radios, computers and phones faster and smaller. But its unique properties have also led to difficulties in integrating the material into such devices. In a paper published Sept. 1 in the journal Nature, a group of UCLA researchers demonstrate how they have overcome some of these difficulties to fabricate the fastest graphene transistor to date. With the highest known carrier...

Strain-gating Researchers at the Georgia Institute of Technology have developed a new class of electronic logic device in which current is switched by an electric field generated by the application of mechanical strain to zinc oxide nanowires. The devices, which include transistors and diodes, could be used in nanometer-scale robotics, nano-electromechanical systems (NEMS), micro-electromechanical systems (MEMS) and microfluidic devices. The mechanical action used to initiate the strain could...

A transistor, made of a solid piece of semiconductor material, is a semiconductor device used to amplify and switch electronic signals. It has at least three terminals for connection to an external circuit. A voltage or current applied to one pair of transistor's terminals changes the current flowing through another pair of terminals. The transistor amplifies the signal since the controlled power can be much more than the controlling power. The transistor is a fundamental building block of...
