Carbon Nanotube Technology Exceeds 100GHz

Carbonics, Inc. has announced that carbon nanotube technology has for the first time achieved speeds exceeding 100GHz in-radio frequency (RF) applications, the company said.

The milestone eclipses the performance — and efficiency — of traditional RF-CMOS technology that is ubiquitous in modern consumer electronics including cell phones. The news opens the door for this new technology to potentially provide a powerful boost for 5G and mm-Wave technologies.

For nearly two decades, researchers have theorized that carbon nanotubes would be well suited as a high-frequency transistor technology due to its unique 1-dimensional electron transport characteristics. The engineering challenge has been to assemble the high purity semiconducting nanotubes into densely aligned arrays and create a working device out of the nanomaterial.

Carbonics employs a deposition technology called ZEBRA that enables carbon nanotubes to be densely aligned and deposited onto a variety of chip substrates including silicon, silicon-on-insulator, quartz and flexible materials. This allows the technology to be directly integrated with traditional CMOS digital logic circuits and overcomes the typical problem of heterogeneous integration.

In 2014, Carbonics was spun-out from the joint center of UCLA-USC and King Abdulaziz City for Science and Technology (KACST) called the Center of Excellence for Green Nanotechnologies and academic funding support from SRC, DARPA and the US Air Force.

Carbonics aims to revolutionize the billion-dollar RF semiconductor market by employing CMOS plus carbon towards a single 5G wireless chip to vastly improve the power consumption and performance of 5G and mmWave products. For more information, visit carbonicsinc.com.
