TWO-DIMENSIONAL MOLECULAR CRYSTALS FOR HYBRID QUANTUM SOLIDS
Abstract
The main aim of this proposal is to develop hybrid quantum solids with previously unavailable physical and quantum mechanical properties by engineering and integrating two-dimensional (2D) atomically thin crystals, including 2D molecular crystals (2DMCs). Our proposed 2DMCs have repeating units based on molecules or superatoms much larger than atoms in conventional inorganic 2D crystals. To achieve our goal, we propose to develop the wafer-scale syntheses of high-quality 2DMCs, investigate their structures and properties using advanced characterization methods, integrate them with conventional 2D inorganic crystals to form custom-designed solids, and predict and realize their exotic electrical, optical, thermal properties. The proposed work will lead to quantum materials platform based on inorganic and molecular crystals for the first time. We will generate powerful suite of capabilities needed for the synthesis, patterning, integration, and characterization of this versatile platform. In addition, we will develop a powerful combinatorial approach which will dramatically accelerate the production and characterization of a large essay of designed solids. The success of this proposal will lead to a new paradigm in novel material design and discovery of unique functions. Our proposal also addresses key needs with AFOSR relevance toward providing new materials with extreme properties currently not available. Large scale thermal conductors with extreme anisotropy can be used to improve the thermal efficiency of power-intense integrated circuits and to produce a super-heater that heats the neighboring surface with minimum energy input. This can be useful for rapid deicing of an airplane, for example. The proposed materials can be used to produce atomically-thin, 2D optical waveguides. They could lead to thin film optical circuitry where light-matter interaction can be patterned and integrated much like in electrical integrated circuits. Finally, the expected charge localization and strong electron-electron interactions in 2DMCs could lead to novel electronic devices, where different electron spatial configurations (lattice) can be used for multi-state memory and sensing.
