high quality SiC layer onto low cost Si wafers), with the ability to pattern and etch this material using a plasma and finally to use novel low-temperature technology to synthesise graphene on only the required pattern.
The researchers say that the combination of a crystalline SiC core with a surface graphene coating is ideal for sensing devices. The exceptional mechanical properties of SiC (which is the second hardest material after diamonds) can be further enhanced by graphene, resulting in excellent fracture strength. Additionally, graphene offers a wealth of surface chemistry approaches for targeting specific ions and molecules.
Earlier this year, the team produced SiC micro- resonators by replacing the traditional metals with a one molecule thick, transparent, highly conductive graphene layer. This work was detailed in a paper called ‘Microresonators with Q-factors over a million from highly stressed epitaxial silicon carbide on silicon’ by A.R Kermany et al in Applied Physics Letters 104, 081901 (2014).
consumption will grow faster at 116.5 percent during the same period to reach 72 ton in 2020, says the report ‘Quantum Dot (QD) Market - Global Analysis, Growth, Trends, Opportunities, Size, Share and Forecast through 2020.’
Drivers for growth include efficient conversion of solar energy into power and rising use of volume- driven display devices. Additionally, the technology is more efficient than conventional technologies.
“The QD display market is set to grow exponentially as many companies such as Sony Corporation, LG Display etc. are getting into alliance with QD technology providers to commercialise QD displays, especially TV sets,” note analysts Shreyas Naidu and Priyanka Gotsurve.
However, some factors such as high cost of technology and slow adoption due to extended research are serving as the restraints for the market growth. Although, mass manufacturing and bulk purchasing will quickly negate the cost constraints. The further penetration of the technology in newer applications such as security & defence, food, and packaging will provide the essential future growth thrust to the market.
Quantum dot market to reach $5 billion by 2020 Solar power and displays driving demand
North America has the highest revenue share due to early adoption. The region is expected to grow consistently and attain revenue of $1.92 billion by 2020. However, Asia-Pacific is expected to have the highest CAGR of 30.4 percent for the analysis period 2013-2020.
