Aixtron AG is a provider of deposition equipment to the semiconductor industry. The company's technology solutions are used to build advanced components for electronic and opto-electronic applications based on compound, silicon, or organic semiconductor materials.
For graphene development and production, Aixtron offers the BM Pro systems (previously called Black Magic systems). BM Pro systems can be used to deposit graphene using both chemical vapor deposition (CVD) and plasma enhanced chemical vapor deposition (PECVD).
Aixtron trades in the Frankfurt Stock Exchange, and in the NASDAQ Stock Exchange (AIXG).
The latest Aixtron graphene news:
Aixtron announced today that China's National Center for Nanoscience and Technology (NCNST) ordered a BM R&D system to grow graphene and CNTs on 2" substrates.
Dr. Qing Dai from NCNST says that their research currently focuses on the characterization of CNTs and on plasmonic properties of graphene. They aim to build nanophotonic devices such as terahertz waveguides. The BM system will also be used to grow 3D nanostructures combining CNT and graphene.
Aixtron announced today that the University of Massachusetts (UMass) ordered a BM-4 deposition system for processing 4-inch substrates. The BM-4 was shipped to the University’s Emerging Technologies and Innovation Center (ETIC).
The system will be used for the integration of carbon nanotubes (CNT) and graphene into a large variety of electronic applications ranging from high frequency transistors, energy storage and flexible electronics. Aixtron says that the BM is a highly flexible system which can deposit both graphene and CNT materials with precisely controlled critical surface dimensions. The BM system also features automatic process control, easy recipe editing, an integrated process camera and remote operation via TCP/IP networking.
The wall street journal posted an interesting article and video on graphene. The article discusses the current state of research and business, possible graphene applications and the rush to patent related technologies.
The article starts with the Cambridge graphene research center and then discusses several companies and their graphene programs, including IBM, Nokia, BlueStone Global Tech, Vorbeck Materials, Lockheed Martin and Aixtron.
Researchers from Japan's AIST and NIMS institues developed a new low power graphene transistor design and produced a working prototype. The new transistor is based on a new operation principle, where two electrodes and two top gates were arranged on the graphene, and crystal defects were introduced by irradiating a helium ion beam on the graphene between the top gates.
In this transistor charge movement can be controlled efficiently by applying an independent voltage to the two top gates. Transistor polarity can be reversed by electrical control. That's the first transistor that can do this.
Aixtron announced that China's Zhejiang University has ordered an AIXTRON BM 2-inch R&D system. The system (which was ordered in Q2 2012 and which will be delivered in Q4 2012) will be used for advance CNT and graphene research.
The BM R&D system features a high performance, fast response heater (1000° C/minute ramp rate) which enables complex process steps at different temperatures to be reproducibly implemented, such as catalyst pre-annealing, growth and post annealing.
