Abstract
A novel thermoelectric cooling/heating device was proposed and fabricated as an alternative to the conventional π-type device. The novel device is the first since the conventional π-type structure was fabricated a half-century ago. The structure includes a sharp tip that is positioned between p- and n-type Bi2Te3 bulks, and the tip can easily be exchanged when different targets are cooled or heated. The tip sizes are 50-100 µm when a copper tip is used and 100 nm when a cantilever is used. The tip temperature reached −36.3 °C during cooling and 251.5 °C during heating. Our device is useful not only for cooling/heating micro-objects but also for heat manipulation of micro-organisms.
