Objectif
The aim of the proposed project is to initiate a new research line on the development of nano-diamond building blocks for micro-devices. Diamond is a superlative engineering material combining exceptional thermal, mechanical, and chemical properties. Nano-grained diamond is of large scientific and technological interest since it could lead to several breakthroughs in micro-engineering, like e.g. for the synthesis of micro-electromechanical systems. Such nano-diamond deposits could replace silicon and other well-established materials that are unsuitable under extreme conditions, and could help to tackle the reliability issues due to friction and wear in numerous micro-device applications. This project will address several key aspects related to the growth, structure, and function of nano-diamond deposits that still impede their breakthrough for micro-scale applications.
The key objective is the controlled synthesis of complex-shaped, 3-D micro-structured nano-diamond deposits with large aspect ratio displaying very low surface roughness, high film conformality, and well-controlled material properties. That will be achieved by acquiring a deeper understanding and control of the early stage formation of nano-diamond thin films on micro-patterned substrates.
The Fellow will combine advanced diamond growth techniques with new developments in atomic layer deposition and miniature device fabrication. He will develop a two-pronged approach using experimental procedures and computer simulations to understand and tailor the nucleation and growth dynamics of nano-diamond thin films. Surface micromachining technology will then be applied for micro-patterning the nano-diamond. For the first time, recently developed micro-device tribometers will be used to assess the tribomechanical performance of nano-diamond at micro-contacts. The research will be carried out in four subprojects axed around two specific applications: (1) micro-fluidic delivery systems and (2) micro-machines.
