Semiconductor nanowire electromagnetic radiation sensor |
摘要 |
A semiconductor nanowire is coated with a chemical coating layer that selectively attaches to the semiconductor material and which forms a dye in a chemical reaction. The dye layer comprises a material that absorbs electromagnetic radiation. A portion of the absorbed energy induces electronic excitation in the chemical coating layer from which additional free charge carriers are temporarily donated into the semiconductor nanowire. Thus, the conductivity of the semiconductor nanowire increases upon illumination on the dye layer. The semiconductor nanowire, and the resulting dye layer collective operate as a detector for electromagnetic radiation.
