Home > Press > Strengthening fragile forests of carbon nanotubes for new MEMS applications

Abstract:
Microelectromechanical systems (MEMS) are incredibly tiny devices, often built on the scale of millionths of a meter. Conventional MEMS structures tend to be made out of silicon-based materials familiar to the micro-electronics industry, but this ignores a suite of useful materials such as other semiconductors, ceramics, and metals. By using a variety of materials not commonly associated with MEMS technology, a team from Brigham Young University (BYU) in Provo, Utah has created stronger microstructures that can form precise, tall and narrow 3-D shapes - characteristics that were never before possible in MEMS. The researchers will present their latest findings at the AVS 59th International Symposium and Exhibition, held Oct. 28 - Nov. 2, in Tampa, Fla.

Strengthening fragile forests of carbon nanotubes for new MEMS applications

College Park, MD | Posted on October 27th, 2012

o break the MEMS materials barrier, the researchers devised a new production process called carbon nanotube templated microfabrication (CNT-M). It uses patterned, vertically aligned carbon nanotube arrays called forests as a 3-D microfabrication scaffold. With this scaffold, the researchers can create precise, tall and fine-featured microstructures. But the forests are extremely fragile. To make them hardier the team replaced the air spaces between the carbon nanotubes with a filler material by atomistic deposition.

The team has used their new CNT-M framework to fabricate metal components from tungsten, molybdenum and nickel. These metals provide desirable properties for MEMS applications and components, including high electrical and thermal conductivity, high melting temperatures, resistance to corrosion, low thermal expansion and hardness.

The BYU team's advances open the door for manipulating matter in novel ways that optimize efficiency, performance and cost across a range of fields, including medicine, imaging, computing, materials synthesis, chemical synthesis, and printing. Most biological and biomedical processes occur at the nanoscale. Developing models and templates at this scale enables scientists to interact with, control and leverage the unusual physical, chemical, mechanical, and optical properties of materials in naturally tiny systems.

Already, the BYU researchers have successfully used their new technique to make chemical detection devices that can validate chemical reactions during pharmaceutical production. Team member Robert C. Davis, PhD , imagines that one day CNT-M might even play a role in devising new longer-lasting batteries.
