Graphene gets another real use – blue LED fabrication

Following a recent graphene oscillator demonstration by UK scientists, Researchers at IBM have used graphene in a re-usable substrate for making blue LEDs.

“In principle, graphene has been demonstrated as an infinitive source for growing these [GaN] semiconductor materials, making the work an enormously cost-effective and reliable production…

Displays get laser treatment

Glass surface coatings can be heated to 1,000°C and be cool 100ms later using a production line laser developed by German firm LIMO.

The machine has been developed to temper coatings on displays in phones and tablets, as well as anneal crystals in coatings and activate dopants.

Such…

Sub-picoamp input op-amp offers high gain bandwidth

Linear Tech is aiming at high-impedance sensor transimpedance amplifiers with an op-amp that requires only 3fA of bias current (typical at 25°C) while offering 500MHz gain bandwidth product.

Potential applications for the chip, called LTC6268, include interfacing ADCs to reverse leakage (linear) mode photodiodes. 20kΩ transimpedance gain…

Prepare for IEC 62368 with X capacitor safety discharger

With IEC 62368 replacing earlier safety standards for TVs and IT equipment, Power Integrations is certifying its X capacitor discharge ICs to the new standard.

X capacitors control conducted emissions from equipment, and are connected straight across the incoming mains – meaning that residual charge in them could cause electric shock…
