DNA Origami Nanoscale Breadboards Developed For Carbon Nanotube Circuits Nov 11, 2009
The "field effect" is useful because "the two components of the transistor, the channel and the gate, don't actually have to touch for there to be a switching effect," Rothemund explains. "One carbon nanotube can switch the conductivity of the other due only to the electric field that forms when a voltage is applied to it.". (Science Daily)
Bay or Holliday? » Nov 8, 2009
But after taking a closer look at three key factors -- the Coors Field effect, performance late in games and on-base ability -- the decision is not so clear ... First, a note on the Coors Field effect. (ESPN -- Baseball)
IEDM to detail SRAM research firsts Oct 28, 2009
Meanwhile, another late paper by Penn State, Cornell and IQE Inc. researchers will describe an interband tunneling field effect transistor (TFET) built on InGaAs. It features on-current of 20 A/ m at 0. (EETimes)
IEDM offers most recent research nuggets Oct 16, 2009
This year, Intel researchers will describe InGaAs quantum-well field effect transistors (QWFETs) with an integrated composite high-k dielectric for reduced gate leakage. Meanwhile, Purdue University researchers will describe a new damage-free dry/wet etching process with which they built the first InGaAs FinFETs. (EETimes)
45-nanometer Chips For Ultra-fast WiFi Aug 14, 2009
With that in mind, Decoutere s team carried out groundbreaking research on 45nm CMOS built using FinFETs, a type of multigate field effect transistor in which the conducting channel is wrapped around a thin silicon fin. To our knowledge, the consortium has created the first complex sub-circuits in FinFET CMOS technology, proving that it is a viable contender [to planar CMOS] for RF applications beyond 45nm, Decoutere explains.

Nanotubes Weigh A Single Atom Jul 24, 2009
So we have the single electron transfer concept, which is more sensitive, and the field effect transistor concept, which is faster. Single atoms. (Science Daily)
'Normal' cells far from cancer give nanosignals of trouble Jul 8, 2009
The findings, obtained using an optical technique that can detect features as small as 20 nanometers, validate the "field effect," a biological phenomenon in which cells located some distance from a malignant or premalignant tumor undergo molecular and other kinds of abnormal changes. The most striking findings were that these nanoscale alterations occurred at some distance from the tumor and, importantly, could be identified by assessing more easily accessible tissue, such as the cheek for lung...

Five enablers for future chip scaling Jun 27, 2009
Intel recently demonstrated a high-speed, low-power quantum well field effect transistor. The p-channel structure will be based on a 40-nm indium antimonide (InSb) material. (EETimes)
Colon Cancer Screening Technique Shows Continued Promise In New Study Jun 16, 2009
"If you have a precancerous lesion in one part of the colon," said Backman, "even tissue that looks normal and is located far from the lesion or polyp will have molecular and other kinds of changes. It's the biological phenomenon called the 'field effect.' No one can detect these changes earlier than we can.". The study examined tissue from 219 patients. (Science Daily)
Faster computers, electronic devices possible after scientists create large-area graphene on copper May 8, 2009
The team then created dual-gated field effect transistors with the top gate electrically isolated from the graphene by a very thin layer of alumina, to determine the carrier mobility. The devices showed that the mobility, a key metric for electronic devices, is significantly higher than that of silicon, the principal semiconductor of most electronic devices, and comparable to natural graphite.

Optical techniques show continued promise in detecting pancreatic cancer Mar 3, 2009
The technology makes use of a biological phenomenon known as the "field effect," a hypothesis that suggests the genetic and environmental milieu that results in a neoplastic lesion in one area of an organ should be detectable throughout the organ and even in neighboring tissue. If similar results are found when the technique is applied to other organs, the method could have broad impact on the timely treatment of breast cancer, lung cancer and other forms of cancer.
