EAGER: Synthesis, Material Investigation and Device Effect Demonstration of Nano Diamond Wires

本计画的目标是开始探索一种新的碳-金刚石纳米线同素异形体的可行性、相变条件及生长机制。 通过这次探索，该团队将试图建立对基础科学的理解，以及金刚石纳米线可重复生长的合成过程。 将通过合成、材料表征和器械效果证明的迭代循环来实现目标。 所提出的项目的智力价值在于证明合成一种新形式的碳-金刚石纳米线的存在和可行性，理解它们的合成显然只能在非常低的温度和压力下进行，这两者都大大低于金刚石-石墨相变所需的相应条件。这项早期概念研究的成功完成可以帮助C60，碳纳米管和石墨烯等广泛的碳电子革命取得进一步进展，只是这次是在钻石（SP3键）方面。这将有助于丰富经典的相变理论与纳米尺度的毛细压力和表面电荷的影响，在纳米制度。该研究项目的更广泛的影响预计在两个主要领域：1）在金刚石-石墨相变的纳米尺度制度的基础科学的进步，2）美国，韩国，澳大利亚和多米尼加共和国之间的国际合作，许多学生参与并为实现另一种新形式的碳纳米结构金刚石纳米线的共同目标做出贡献。

The objective of this program is to begin the exploration of the feasibility, phase-transition conditions and growth mechanism of a new allotrope of carbon diamond nanowires. Through this exploration, the team will try to establish an understanding of the basic science underlying and a synthetic process for reproducible growth of diamond nanowires. The objective will be met through iterative cycles of synthesis, materials characterization, and device effect demonstration. The intellectual merit of the proposed project is in proving the existence and feasibility of synthesizing a new form of carbon - diamond nanowires, in understanding their synthesis that apparently could take place so-far only at an extraordinarily low temperature and pressure, both of which being greatly lower than the corresponding conditions known as required for the diamond-graphite phase-transitions. Successful completion of this Early-Concept study could help door to further advances in the broad carbon-electronic revolution exemplified by C60, carbon nanotube, and graphene, only this time on the diamond (SP3-bond) side of the family. It could help enrich the classical phase-transition theory with the effects of nano-scale capillary pressure and the surface charges in the nano-regime. The broader impact of this research project are expected in two primary areas; 1) The advancement of fundamental science in the nano-scale regime of the diamond-graphite phase-transitions, 2) international collaboration between USA, Korea, Australia, and Domenico Republic, with many students participating and contributing to the common goal of bringing to existence of yet another new form of carbon nanostructures diamond nanowires.
