研究了小面积薄膜金属-金属氧化物-金属（Metal-Metal Oxide-Metal，简称MIM）结构探测辐射的机理。结果表明，扣除热效应后，光学频率下的响应来自氧化物势垒上的光发射。在较低的频率下，该机制源于整流过程，该整流过程由跨结的电子隧穿引起的非线性I-V特性决定。
The mechanism of detection of radiation by a small‐area thin‐film metal‐metal oxide‐metal (MOM) structure is studied. It is shown that after subtracting thermal effects the response at optical frequencies arises from photoemission over the oxide’s potential barrier. At lower frequencies the mechanism arises from a rectification process dictated by the nonlinear I‐V characteristics due to electron tunneling across the junction.
