Imprinting electronic circuitry on backplanes that are both flexible and stretchable promises to revolutionize a number of industries and make “smart devices” nearly ubiquitous. Among the applications that have been envisioned are electronic pads that …
Like snowflakes or fingerprints, no two quantum dots are identical. But a new etching method for shaping and positioning these semiconductor nanocrystals might change that. What’s more, tests at the National Institute of Standards and Technolo…
In the quest to develop flexible plastic electronics, one of the stumbling blocks has been creating transistors with enough stability for them to function in a variety of environments while still maintaining the current needed to power the devic…
Scientists from the Kavli Institute of Nanoscience at Delft University of Technology and Eindhoven University of Technology in The Netherlands have succeeded in controlling the building blocks of a future super-fast quantum computer. They are now …
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 semicond…
The ability to make atomic-level changes in the functional components of semiconductor switches, demonstrated by a team of Oak Ridge National Laboratory, North Carolina State University and University of Tennessee physicists, could lead to huge changes in the semiconductor industry. The results are reported in the June 13 issue of Science.
Evident Technologies, Inc. announced today that it has been issued United States Patent Number 6,571,028 for an all optical switch or optical transistor. The optical transistor is based upon a saturable absorber or switch using the company?s EviDots semiconductor nanocrystal quantum dot technologies. The optical switch has the potential to switch at speeds up to thousands of times faster than current generation optical switching.
A basic discovery in magnetic semiconductors could result in a new generation of devices for sensors and memory applications — and perhaps, ultimately, quantum computation — physicists from the California Institute of Technology and the University of California at Santa Barbara have announced. The new phenomenon, called the giant planar Hall effect, has to do with what happens when the spins of current-carrying electrons are manipulated. For several years scientists have been engaged in exploiting electron spin for the creation of a new generation of electronic devices –hence the term “spintronics” — and the Caltech-UCSB breakthrough offers a new route to realizing such devices.
The quantum entanglement of three electrons, using an ultrafast optical pulse and a quantum well of a magnetic semiconductor material, has been demonstrated in a laboratory at the University of Michigan, marking another step toward the realization of a practical quantum computer. While several experiments in recent years have succeeded in entangling pairs of particles, few researchers have managed to correlate three or more particles in a predictable fashion.
