[more ▼] The co-electrodeposition of copper and indium from a pH 3 tartrate bath onto 4.8 cm × 2.5 cm Mo and MoSe2 substrates is studied and conditions are optimised for CuIn alloy films. Selenisation at ca. 500 °C for 30 min in selenium vapour gives CuInSe2 (or CISe). Mapping using the photo-electrochemical reduction of Eu(NO3)3 is used to asses the relative photoactivity as a function of position and surface treatment.Etching of detrimental CuxSe phases is investigated with 5% and 0.5% (w/w) aqueous KCN. The slower 0.5% (w/w) KCN etch allows better process control, and re-annealing at 500 °C for 30 min followed by further etching significantly improved the photo-activity. However, over the large area local pinhole recombination effects are substantial. An alternative low temperature film optimisation method is proposed based on (i) KCN over-etch, (ii) hypochlorite (5%, w/w) pinhole removal (Mo etch), and (iii) a final KCN etch to give good and more uniform activity.

[more ▼] A bioelectronic interface based on the coupling of an intact insect antenna to a field-e effct transistor (FET) has been realised in a whole-beetle BioFET (Biologically sensitive FET) and an isolated-antenna BioFET configuration. The intrinsic BioFET characteristics, such as current-voltage curves, transconductance and signal-to-noise ratio clearly depend on the chip layout. Therefore, the experiments were performed with three di erent gate geometries: linear shape (5 um x 100 um), U shape (5 um x 1000 um) and meander shape (10 um x 6000 um). The BioFET allows the determination of the `green-leaf odour' Z-3-hexen-l-ol down to the low ppb concentration range. Thus, the detection of plant damages is possible with this novel kind of biosensor. [less ▲] Detailed reference viewed: 177 (0 UL) |
