We introduce, a complementary carbon nanotube (CNT)-gated CNT thin-film field effect transistor (FET). By using two perpendicularly crossed single-wall CNT (SWNT) bundles as the gate and the channel interchangeably, a sub-50 nm complementary CNT-FET is demonstrated. It is found that the new CNT-FET shows acceptable FET characteristics by interchanging the roles of the gate and the channel. The unique dual functionality of the device will open up a new possibility and flexibility in the design of future complementary CNT electronic circuits. (c) 2006 American Institute of Physics.

Lateral-growth carbon nanotubes (CNTs) were fabricated in a pre-assigned area using an integrated circuit compatible method. In order to synthesize single wall carbon nanotubes (SWNT) for the fabrication of a field-effect transistor (FET), the cobalt-mix-tetraethoxysilane (TEOS) (CMT) solution is proposed. The CMT solution has the unique property of dispersing the cobalt (Co) catalyst well and uniformly embedding it in a predetermined location after the CMT solution has solidified. The lateral growth of bundle-SWNT could be formed in atmospheric chemical vapor deposition (APCVD) with ethanol. (c) 2005 The Electrochemical Society.

Most of the research on ''distance learning on the Web'' is learner-centric. That is, learners play an active role in their learning process, while instructors are passive oi even invisible. Unable to treat the instructor/learner relationship as a whole causes some problems. Therefore, we introduce a new concept of instructor-oriented navigation control on the Web, and then propose and implement a protocol for it. In this model, an instructor (technically, master) can setup a learning group, and those who wish to be guided distantly (technically, slaves) during the study may have their navigation activities controlled synchronously by joining the group. We believe that instructors will become more active and positive with the help of our proposed model in a WWW-based educational environment.
