Computer Tech Update

Gigahertz radar on chip

• 5 x 5 mm radar transceiver chip for distance sensing– Nanosecond short pulses– Has 64 radar shells, can track up to 64 things at

once.– It can also see through same materials at this

frenquency range.– Can detect down to mm range

Organic Eletronics

• Pentagonal tiles self assembly of organic building blocks– Ring like molecules with five fold symmetry• Copper substrate strong bonding• Weaker interaction with neighbors

– Perfect for creating self assembling high-density thin films

– Applications in computing, solar power, display technologies.

High Temperature SpintronicsCommercial (85 C), industrial (100 C), and military application (125 C) temperature viability achieved. Stable up to 235 C.

Key step for general devices relying on electron spin rather than electron charge.

$1.5 billion graphene R&D

• Target at applications and manufacturability (European project)

• Graphene advantages– High strength and flexibility• Twist and flex without breaking

– High conductivity and optical transparency• Touchscreens, LCDs, OLEDs. Alternative to indium tin

oxide

Intel mass production: trigate transitors

Active Optical Nanoantennas

Future of OLED TV

Tiny transistor, artificial atom

Plasmonic Resonance in Nanocrystals

• For the first time plasmonic resonance has been shown in semiconductors– Allows much more direct coupling of electronic

and photonic devices
