3M and IBM announced that the two companies plan to jointly develop the first adhesives that can be used to package semiconductors into densely stacked silicon “towers.” Processors could be tightly packed with memory and networking, for example, into a “brick” of silicon that would create a computer chip 1,000 times faster than today’s fastest microprocessor enabling more powerful smartphones, tablets, computers and gaming devices.

Taking a cue from ‘whispering galleries’ built into cathedrals by Renaissance architects, researchers at the University of Pennsylvania adapted the principle to nanoscale devices to drastically reduce emission lifetime, a key property of light-emitting semiconductors. A whispering gallery is a circular chamber designed to reflect and direct sound waves so that a whisper can be heard across the room.

When a semiconductor material is excited, it takes a few nanoseconds to return to the ground state, which is accompanied by emission of light. This delay is called the emission lifetime. For devices such as modulators, which must switch back and forth between two states, the emission lifetime sets a limit to the switching rate. The novel approach taken by the researchers reduces the emission lifetime to less than a picosecond – more than a thousand times faster than anything else currently available. [via]
