Thermoelectric infrared detector

摘要

A thermoelectric infrared detector comprising a substrate and two kinds of conducting pillars. The pillars longitudinally extend away from the substrate towards incident infrared radiation. The pillars have upper, hot ends remote from the substrate and lower ends at the substrate. Pairs of adjacent pillars of different kinds are electrically connected by a conducting junction at their upper ends, and thereby define thermocouples. The junctions of different pairs of pillars are exposed to the incident radiation.
