Накратко на български
Двуизмерни материали се използват за създаване на гъвкави сензори, които улавят различни инфрачервени сигнали едновременно. Те ще помогнат за по-евтин контрол на опаковките, бърза медицинска диагностика в отдалечени райони и сигурна комуникация между домашни уреди.

Flexible Hyperspectral Infrared Detectors
The ambition set out in the proposal of the FLAIR project was to introduce a disruptive concept for hyperspectral imaging, that will enable mid- and short-wave infrared signals to be recorded simultaneously using a single detector. To truly be a game changer, FLAIR needs to be designed based on cutting-edge technology offered by emerging atomically-thin (2D) materials as these will allow it to be imperceptible, flexible and durable. Combining all of these attributes, FLAIR will form a versatile platform, suitable for inclusion in packaging, and in disposable probes for medical diagnostics, as well as in robust systems such as security cameras. To achieve these goals, the FLAIR platform is based on online modulation of the energy barriers in 2D materials, coupled with their enhanced properties of light-matter interaction. As the pool of target material expanded, broader potential for societal impact emerged, since the FLAIR detector platform could now be tailored to access a wider range in the electromagnetic spectrum. Amongst the societal benefits offered by this novel platform, we are expecting to see emerging technologies that will allow: 1. Online, low-cost monitoring of packaging integrity for security in various sectors, ranging from food to homeland security. 2. Point-of-care diagnostics for remote and rural area, that will give reliable information and timely response to both patients and care providers. 3. Further integration with household items, to allow for secure, short-distance autonomous communication (Internet of Things). To deliver goals set for the FLAIR platform, we have set the following objectives: 1. Develop wavelength-specific energy barriers in 2D semiconductors 2. Study the photoresponse and electrical characteristics of 2D semiconductors

Цел на проекта
One of the major driving forces for current research in electronics is the desire to realize the so-called internet of things, an autonomous information network that enables communication between objects without external human intervention. To this end, much of the research effort in device physics is currently directed into sensors technology, and specifically, to photodetectors. The infrared (IR) region of the spectrum is of particular interest as it can carry information about an object’s temperature, and its chemical composition. IR waves are also used for long-range waveguided communication, as well as short-range free space signaling. In IR systems, the readout noise is reduced by exploiting multicolor IR detection, so-called hyperspectral IR, thus lowering false positive detection.Nowadays, IR detectors are not transparent in the visible wavelength and they are made of brittle materials. Hence their potential in technology such as food and drug packaging, textile fabrics-embedded devices for health care and homeland security systems, has yet to be realized. In this proposal we will harvest the unique potential of emerging atomically thin materials to pioneer a new class of flexible hyperspectral infrared detectors (FLAIR) which are imperceptible to the human eyes and yet highly efficient. These FLAIR detectors will consist of a layered structure with an active graphene bilayer, sandwiched between two dielectric h-BN layers and two outer gates made of heavily doped graphene. The top gate will be patterned as a continuous array of anti-discs to enhance the light absorption at the plasmon excitation frequency. A perpendicular electric field applied to bilayer graphene will be used to open a tuneable energy gap unique to this material and cut off the absorption of the lower frequencies to ensure a superior signal-to-noise ratio. Arrays of detectors with different plasmon absorption frequencies will enable the hyperspectral response of the device.
