摘要:

A field-effect transistor with metal gate suspended above the gate insulator has been fabricated. Fluid samples can freely penetrate into the gap formed between the metal and the insulator. If the molecules carry an electrical dipole, they will alter the surface potential on these two materials giving rise to a change in the drain current of the transistor. Our preliminary results confirm this mechanism for dipolar molecules such as methanol and methylene chloride.

摘要:

New experimental results of very stable field emitted electrons from TiC single crystal needles are presented. The optimum flashing temperature region for the stable field emission was found. The stability, which is defined by the ratio of current fluctuation to total current, was better than 0.5% at a vacuum of 10−7Pa with total electron emission of 1 &mgr;A.

摘要:

This letter reports a new electrochromic polymeric film system consisting of a polymer, an electrochromic (EC) dye which is pyrazoline or tetrathiafulvalene (TTF), and lithium perchlorate (LiClO4). The electrochromic cell structure is glass/ITO/polymeric EC film/Au film. The cell using pyrazoline as an EC dye exhibited yellow coloration at 1.0 V and the cell with TTF exhibited red coloration at 3.5 V. These cells exhibited memory.
