A quantum dot energy harvester
Date:2/14/2013

means the quantum dots act as perfect energy filters. When the system is in the resonant tunneling mode, electrons can only pass through the quantum dots when they have a specific energy that can be adjusted. All other electrons that do not have this energy are blocked.

Quantum dots can be grown in a self-assembling way out of semiconductor materials. This allows for a practical way to produce many of these tiny engines as part of a larger array, and in multiple layers, which the authors refer to as the Swiss Cheese Sandwich configuration.

How much electrical power is produced depends on the temperature difference across the energy harvester the higher the temperature difference, the higher the power that will be generated. This requires good insulation between the hot and cold regions, Jordan says.
