摘要：

Obtaining low temperature crystallised NiTi films would ensure a good compatibility with microelectronics processes and allow deposition on substrates that could not endure high temperatures, like polymers. We found that NiTi films containing an excess of Ti (52% at.) are crystallised when deposited on Si(100) substrates heated up to only 200 degrees C. Resistance vs. temperature measurements show typical martensitic transformation behaviour. By depositing this type of films on polyimide substrates, we obtain bimorph micro-actuators exhibiting a two-way shape memory effect. (C) 1999 Elsevier Science S.A. All rights reserved.
