1. MEMS/NEMS based novel biomedical devices

The ability to detect bio-molecule at ultra-low concentrations (e.g. atto-molar) will enable the possibility of detecting diseases earlier than ever before. A critical challenge for any new bio-sensing technology is to optimize two metrics --- shorter analysis time, and higher concentration sensitivity in clinically relevant small volumes. Moreover, practical considerations are equally important: simplicity of use, mass producible (low cost), and ease of integration within the clinical structure. Compared with other methods, nano-electro-mechanical system (NEMS) based bio-sensors are promising in clinical diagnostics because of their extremely high mass sensitivity, fast response time and the capability of integration on chip. We have demonstrated a low concentration DNA (atto-molar sensitivity) optically interrogated ultrasonic mechanical mass sensor, which has ordered nanowire (NW) array on top of a bilayer membrane. This method represents a mass-based platform technology that can sense molecules at low concentrations, which could be useful for early-stage disease detection. We can develop this sensor further to measure an array of biomarkers (e.g. DNA or proteins), by providing both the needed specificity and sensitivity in physiological disease (e.g. cancer) detection.

2. Atomically thin opto-electronic devices (LED, solar cells) and/or mechanical devices based on novel two dimensional nano-materials

Two-dimensional (2D) nano-materials, such as molybdenum disulfide (MoS2) and graphene, have atomic or molecular thickness, exhibiting promising applications in nano-electro-mechanical systems. Graphene is a one-atom thick carbon sheet, with atoms arranged in a regular hexagonal pattern. Molybdenum disulfide (MoS2) belongs to transition metal dichalcogenides (TMD) semiconductor family YX2 (Y=Mo, W; X=S, Se, Te), with a layered structure. This project aims to demonstrate novel opto-electronic devices, like light-emitting diode (LED), solar cells, etc. These 2D nano-materials can also be integrated into nano-electro-mechanical systems, enabling ultra-sensitive mechanical mass sensors, with single molecule or even single atom sensitivities. Moreover, the mechanical resonators based on these 2D nano-materials would be a perfect platform to investigate quantum mechanics, opto-mechanics, material internal friction force, nonlinear physics, etc.

3. Optical nonlinearities in 2D crystals

Entangled photons have many applications — from fundamental tests of quantum mechanics, to practical implementations in quantum key distribution, quantum imaging and ultraprecise metrology. Generating entangled photons with broad spectral and angular widths is a long-standing goal in quantum optics. A platform on which to achieve this goal is highly nonlinear atomically thin 2D crystals: due to their scale and optical properties, these two-dimensional crystalline layers can be designed into fully operational, miniaturised quantum photonic chips.

Since the discovery of graphene in 2004, many materials with a stable monolayer form have been found, including the important subclass of transition-metal dichalcogenides (MX2; M = Mo/W; X = S/Se/Te). These materials are centrosymmetric when in bulk form, but the inversion symmetry is broken when thinning them down to monolayer thickness. As a result, 2D monolayers feature an atomic-level dipole that gives them extraordinary physical properties including dichroism, ferroelectricity, and piezoelectricity. In particular, the monolayers exhibit enormous second-order susceptibility χ(2) that enables efficient nonlinear optical processes.

Highly nonlinear 2D materials can in principle be used for spontaneous parametric down-conversion (SPDC). SPDC is a well developed tool in quantum optics to produce entangled photons. So far, this process has exclusively been observed at the macroscopic scale on periodically poled bulk crystals. This project aims to investigate enhancement techniques to bring SPDC to the atomic scale and use nonlinear 2D crystals as integrated highly entangled photon sources.

4. Quantum emitters in 2D materials

Single photon sources are critical for future quantum technologies such as quantum computing, quantum simulators, and unconditionally secure quantum communication.

The recent discovery of quantum emitters in two-dimensional (2D) materials offers a very promising source of single photon sources, with compelling applications for the next generation of integrated photonic devices. In contrast to their 3D counterparts, quantum emitters in amotically thin 2D lattices are not surrounded by any high refractive index medium. This eliminates total internal and Fresnel reflection of emitted single-photons, allowing intrinsically near-ideal extraction efficiency.

Quantum emission has been reported from a diversity of materials, in semiconducting transition metal dichalcogenides (TMDs) and insulating hexagonal boron nitride (hBN). The large band gap of the latter even allows one to resolve the zero phonon line (ZPL) at room temperature and thwarts non-radiative recombination of the localized exciton. Thus, single-photon emitters in hBN have an intrinsically high quantum efficiency which leads to significantly brighter emission. These single-photon sources are suitable for many practical field applications due to their resistance to ionizing radiation, temperature stability over a range spanning 800 K, long-term operation and capabilities for integration with photonic networks, as well as easy handling.
