#IBM-Led Team Pulls Off Major Chip Feat IBM Research on Thursday announced that an alliance it leads has produced the first 7nm node test chips with functioning transistors.
The alliance sought to develop industry-first innovations, such as Silicon Germanium (Sige) channel transistors, and Extreme Ultraviolet (EUV) lithography integration at multiple levels.
The number of transistors in an integrated circuit doubles roughly every two years, according to Moore's Law,
but the semiconductor industry for some years has been concerned that it is fast reaching the upper limit of just how many transistors can be packed into an IC.
Intel apparently expects to be able to build 5nm transistors at some point.""The higher the density of transistors, the more cores you can put in a given space,"noted Rob Enderle, principal analyst at the Enderle Group."
"A very high-density part would be ideal for the cloud, which is why ARM

Capacitors use an electrostatic charge to store energy they can release quickly, to a camera flash, for example.
Unlike chemical-based rechargeable batteries, capacitors charge fast and release all their energy at once when triggered.
Supercapacitors combine useful qualities of both the fast charge/discharge of capacitors and high-energy capacity of batteries into one package.

To show how well their supercapacitors scale up for applications, the researchers wired pairs of each variety of device in serial and parallel.
The vertical supercapacitors showed almost no change in electrical performance when flexed, even after 8, 000 bending cycles.
LIG supercapacitors of the same size offer three times the performance in power (the speed at which energy flows).

#Researchers Build a Transistor from a Molecule and A few Atoms An international team of physicists has used a scanning tunneling microscope to create a minute transistor consisting of a single molecule and a small number of atoms.
The observed transistor action is markedly different from the conventionally expected behavior and could be important for future device technologies as well as for fundamental studies of electron transport in molecular nanostructures.
The positively charged atoms provide the electrostatic gate of the single-molecule transistor. See more at:

In atomic-scale transistors, this current is extremely sensitive to single electrons hopping via discrete energy levels.
In earlier studies, researchers have examined single-electron transport in molecular transistors using top-down approaches, such as lithography and break junctions.
But atomically precise control of the gatehich is crucial to transistor action at the smallest size scaless not possible with these approaches.

The technological advance puts lasers one step closer to being a mainstream light source and potential replacement or alternative to light emitting diodes (LEDS.
In typical LED-based lighting a blue LED is coated with phosphor materials to convert a portion of the blue light to green, yellow and red light.
This mixture of colored light will be perceived by humans as white light and can therefore be used for general illumination.
The researchers showed that the human eye is as comfortable with white light generated by diode lasers as with that produced by LEDS,

The transistor is made of a single molecule of phthalocyanine surrounded by ring of 12 positively charged indium atoms placed on an indium arsenide crystal,
For comparison a strand of human hair, at 100, 000nm thick, is about 600,000 times wider than the atoms surrounding the new transistor.
The transistor represents a big step forward toward quantum computing, and was made possible using a scanning tunnelling electron microscope to place atoms in exact positions
and can jump outside of the transistor, rendering it useless. The international team of researchers from Paul-Drude-Institut für Festkörperelektronik and the Freie Universität Berlin, Germany, the NTT Basic Research Laboratories, Japan,
and the US Naval Research Laboratory also discovered unexpected behaviour from the transistor. The orientation of the molecule of phthalocyanine an organic molecule typically used in dyes at the heart of the transistor is affected by charge.
Its orientation could be changed by altering its charge, leading to more than a simple on-off switch-like state as seen in traditional transistors.
The work proves that precise control of atoms to create a transistor smaller than any other quantum system available is possible
and opens the door to further research into harnessing these tiny transistors for computers and systems with orders of magnitude more processing power than today machines.
Chip manufacturers have struggled to maintain Moore law, which dictates that processing power will double every 18 to 24 months,
