We leverage on our state-of-the-art synthesis capabilities and synthesize hybrid nanomaterials. For example, one can think of combining the nanowire and graphene worlds to form materials with new physical and chemical properties. In our recent published work we were able to demonstrate for the first time the synthesis of in-plane Ge nanowires (or Ge nanocrawlers) on single layer graphene substrates. Since its discovery graphene was used as a platform for synthesis of various materials such as zero-dimensional materials (nano particles), one-dimensional materials (nanowires), two-dimensional materials and polymers. The growth of in-plane nanowires on graphene has not been investigated to-date. Our current work investigates the conditions that will lead to in-plane nanowires growth on graphene, or as we refer to them nanocrawlers. We realized a set of conditions that will end up with high yield of in-plane nanowire growth. We have also developed a thermodynamic model to explain this observation. This basic science study will shed light on crystal growth on graphene and will potentially enable development of hybrid materials that can be used as photo-sensors or electrical devices.
We currently further pursue this direction toward realization of new type of functional hybrid materials!
