Scientists at Rice University believe they are well on the way to making charge coupled devices (CCDs) for imaging that are only atoms thick.
The sythetic materials using metal chalcogenide compounds could lead to the superthin devices with molybdenum disulphide the favourite for its light detecting property. Copper indium selenide (CIS) is also one of the front runners.
Researcher Sidong Lei synthesised CIS, which is a single layer matrix of copper, indium and selenium atoms and built a three pixel CCD prototype to capture an image.
Sidong Lei, a graduate student at Rice, believes the materials could well be an important component in the future. “Traditional CCDs are thick and rigid and it would not make sense to combine them with 2D elements.” The CCDs will be ultrathin, transparent and flexible.
Senior faculty fellow Robert Vajtai agreed and said that none are as efficient as this [CIS] material.
CIS could be incorporaed into curved configurations to match lenses and have applications in a number of fields including bio-medics as well as opto electronics.
A report said that the market for facial recognition is set to see 27.7 percent compount annual growth to 2018, when it will be worth around $6.5 billion.
The research from ReportsnReports.com said the market is segmented into various technologies including 2D, 3D, thermal imaging, “emotion” imaging and mobile.
And the forces driving the market are big spends by governments worlwide on biometric technology.
Companies big in the field include Afix Technologies, Fujitsu, Gemalto, Nextgen and many others. Other multinational corporations surveted include NEC, Qualcomm, Toshiba, Catchroom and Hitachi.
The research company claims that the facial recognition market has come into its own because of 3D technology, better imaging, better sofware and speedier analytics.
The market was worth $1.92 billion in 2013, the company estimates.
