Ultrafast collinear scattering and carrier multiplication in graphene.
in Nature communications
| Description | We gained a full understanding of the kinetic and relaxation properties of charge carriers and lattice modes in graphene following excitation of carries. A detailed picture of the ultrafast dynamics was gained, defining the state of the art in the field. In particular, we identified the role of collinear scattering. This gives rise to Auger processes, including charge multiplication, which is key in photovoltage generation and photodetectors |
| Exploitation Route | This research underpins the understanding of all graphene-based photonic devices exploiting non equilibrium carriers, such as mode-locked lasers, but also has important implications for photodetectors and photovoltage generation. Carrier multiplication could significant enhance the efficiency of these devices. A spin off company, Camlase ltd was funded, to exploit graphene as mode locker in ultrafast lasers. A patent was jointly submitted and application filed with IBM |
| Sectors | Aerospace Defence and Marine Chemicals Construction Digital/Communication/Information Technologies (including Software) Education Electronics Energy Environment Healthcare Manufacturing including Industrial Biotechology Transport |
| Description | This research has significant implications for applications of graphene in lasers, detectors and photovoltaic devices. Indeed, a spin-off was formed and a patent submitted. |

| Title | FUNCTIONAL INKS BASED ON LAYERED MATERIALS AND PRINTED LAYERED MATERIALS |
| Description | An ink disclosed herein comprises a carrier liquid with a dispersion of flakes derived from a layered material. The thickness of each flake depends on the number of layers of the layered material in the flake. The thickness distribution of the flakes includes: at least 20% by number of single layer flakes; at least 40% by number cumulatively of single, double and triple layer flakes; or not more than 40% by number of flakes having ten or more layers. The layered material is selected from one or more of elemental materials such as graphene (typically derived from pristine graphite), metals (e.g., NiTe2, VSe2), semi-metals (e.g., WTa2, TcS2), semiconductors (e.g., WS2, WSe2, MoS2, MoTe2, TaS2, RhTe2, PdTe2), insulators (e.g., h-BN, HfS2), superconductors (e.g., NbS2, NbSe2, NbTe2, TaSe2) and topological insulators and thermo-electrics (e.g., Bi2Se3, Bi2Te3). Also disclosed are methods of manufacturing suitable inks and uses of the inks. |

| Title | OPTOELECTRONIC DEVICE EMPLOYING A MICROCAVITY INCLUDING A TWO-DIMENSIONAL CARBON LATTICE STRUCTURE |
| Description | A microcavity-controlled two-dimensional carbon lattice structure device selectively modifies to reflect or to transmit, or emits, or absorbs, electromagnetic radiation depending on the wavelength of the electromagnetic radiation. The microcavity-controlled two-dimensional carbon lattice structure device employs a graphene layer or at least one carbon nanotube located within an optical center of a microcavity defined by a pair of partial mirrors that partially reflect electromagnetic radiation. The spacing between the mirror determines the efficiency of elastic and inelastic scattering of electromagnetic radiation inside the microcavity, and hence, determines a resonance wavelength of electronic radiation that is coupled to the microcavity. The resonance wavelength is tunable by selecting the dimensional and material parameters of the microcavity. The process for manufacturing this device is compatible with standard complementary metal oxide semiconductor (CMOS) manufacturing processes. |

| Title | Superconducting materials |
| Description | Partially or fully saturated doped graphene materials are found to be superconducting. The saturation is with hydrogen or halogen. Doping is performed by substitution of carbon atoms or by applying an electric field. Diamond nano-rods are also found to be superconducting. These materials can be used in electronic devices having a gate. |
