Well, it looks there's a new challenger about to enter that ring -- double floating-gate field effect transistors, currently in prototype form at North Carolina State University. Whereas the single floating-gate variety is currently responsible for the flash memory in your USB keys and SSDs, the second floating gate lets bits of data stay in an active, ready state, but the computer can also apply a higher voltage to "freeze" them in place. Since the memory can switch between static and dynamic modes in a single cycle and the data never disappears in between, researchers imagine the new tech could lead to instant-on computers and power-saving techniques that shut down idle memory banks. That's the consumer take, at least -- find the technical deep dive at our more coverage link.

Yes, that's a RepRap 3D printer you see there, with a MakerBot Unicorn pen head, depositing tiny dots of silver ink to form intricate rows of tiny electrodes. Sadly, the printer doesn't currently automate the entire process, as you'll also need to separately apply a dielectric material and a host of chemicals to get a working field effect transistor from scratch, but once the basic process is perfected the possibilities, as they say, are endless. Now if you'll excuse us, we've got a hot date with some vacuum tubes. Find the basic formula for DIY transistors at our source link.

IBM now says it's managed to overcome one of the biggest hurdles, however, and has announced that it's been able to open a "bandgap" for graphene field-effect transistors (or FETs). As EETimes reports, that's important because while graphene does have a higher carrier mobility than silicon, it doesn't have a natural bandgap, which has so far kept the on-off ratio of graphene transistors far lower than their silicon counterparts. Of course, IBM insists that its still only just scratched the surface, and says that it's already hard at work on opening up an even wider bandgap, achieving even higher electric fields, further improving the on-off current ratios of graphene FETs.

The company's spin-off Field Emission Technologies, whose sole purpose was to develop the displays, is now closing its doors. Blame goes to difficulty in raising funds for manufacturing. After years of teasing and an actual demo unit just a few months ago, it's a little sad to the technology's biggest proponent shutter. Goodbye, FET, we hardly knew ye.

t's been a hot minute since we've heard anything from Field Emission Technologies, but apparently the Sony spin-off is gearing up to make some serious noise in the industry. Field emission display (FED) still remains a relatively unknown panel technology, but FET is hoping to change all that by introducing a 60-inch display that will be "more energy efficient and sharper than [an] LCD." Analysts assert that FED will actually be a suitable alternative to OLED, and while Sony's own XEL-1 is fine and dandy, that 11-inch screen sort of renders it useless for home theater use. Reportedly, FET is "in negotiation with Pioneer regarding mass-production of field emission displays," and while the first batch of 60-inchers will likely hit hospital wards and TV studios first, you better believe the general public will be next in line.

Yep, turns out that Far EasTone Telecommunications licenses NTT DoCoMo's well-known mobile internet brand for use in Taiwan, and they've partnered with Nokia to deliver the service on a customized version of the 6124 classic candybar -- the first Nokia ever to offer it. Of course, no i-mode handset is complete without blazing data speeds, and sure enough, the 6124 classic delivers with support for HSDPA in addition to a 2 megapixel cam, QVGA display, and S60 3rd Edition Feature Pack 1. Yep, that's right, not only is Nokia tying up with i-mode, they're doing so on an honest-to-goodness smartphone. Kudos!

Seven wireless providers covering eight countries and regions -- NTT DoCoMo (Japan), FET (Taiwan), Hutchison Essar (India), Hutchison Telecommunications (Hong Kong and Macau), KTF (South Korea), Indostat (Indonesia), and StarHub (Singapore) -- have formed the "Asia-Pacific Mobile Alliance," as it's tentatively known, to eventually enable seamless voice, video, and data roaming across their networks. According to the joint press release, when the initiative goes live in the latter half of the year, GSM/GPRS and W-CDMA customers will also enjoy access to the basic services they've become accustomed to, such as caller ID and quick access to voicemail and home carrier tech support via short-code service.
