Quantum Gas Sensing Patent

Описание: This patent describes the implementation of a gas detecting sensor that utilizes quantum dots to identify specific gas concentrations, such as carbon dioxide. The technology functions by matching the in-band electronic transition energy of a quantum dot layer with the vibrational energy of target gas molecules through a process of resonance. When these energies align, the resulting transfer causes a measurable potential difference that is converted into a current change within an n-type channel made of materials like IGZO. This mechanism allows the sensor to translate surface potential variations into electrical signals, such as shifts in threshold voltage, which can be monitored in real time. The integration with thin-film transistors offers a high-efficiency alternative to conventional sensors, reducing energy consumption and warm-up periods. Additionally, the document details how modifying quantum dot ligands can enhance the sensor's sensitivity and stability within the infrared spectrum.
