Korea's DGIST to Produce Individual Carbon Nanotube Arrays With AIXTRON System
(Nanowerk News) AIXTRON SE today announced an order from Daegu Gyeongbuk Institute of Science & Technology (DGIST) in South Korea. The contract is for one BM II (2-inch) system which will be used to deposit carbon nanotube (CNT) arrays for 3D devices, such as nano-antennas, nano-rectifiers and others. The system has already been installed and commissioned by AIXTRON’s local service team.
“The unique devices we are developing require the controlled deposition of individual, vertical aligned carbon nanotubes at precise locations,” Professor Jae Eun Jang from the Department of Information & Communication Engineering at DGIST, comments. “This is where AIXTRON’s plasma-based BM system really stands out against other options we considered. Indeed, the BM system enables us to reliably achieve carbon nanotube growth with unparalleled control over growth parameters and nanotube alignment in a reproducible manner.”
Although research into carbon nanotube devices has progressed significantly over the last decade, the precise control of the number and the location of nanotubes over large areas, (necessary for the production of integrated circuits), is just one of the key challenges. Using AIXTRON’s BM system, DGIST aims to tackle these.
“The BM system enables us to grow a single vertical carbon nanotube with controlled dimensions at pre-defined locations through a process that is compatible with existing silicon technology. The vertical orientation of single nanotubes is a key feature, as it allows us to decrease the device cell area significantly over conventional device approaches. We are applying the use of vertical nanotubes to not only electronic and communication devices, but also to novel applications such as nano-electromechanical and robotic systems,” Professor Jang concludes.
Following his Bachelor of Engineering at Hanyang University (Seoul, Korea), Professor Jang, was awarded his PhD at the University of Cambridge (UK). His main achievements include an "Outstanding Paper Award" at IMID 2010, as well as other awards such as the Samsung Electronics "Innovative Invention Award" in 2009 and the Samsung Best Paper “Silver Award” in 2008. His current research interests include wireless communication systems, 3D electronic devices, sensors, flexible electronics/wearable computers, human interface devices and optical shutters.
