“…The focal plane array ͑FPA͒ imaging systems based on quantum well infrared photodetectors ͑QWIPs͒ have shown the potential use for military, medical, and civil applications. [1][2][3][4] However, the main drawback of the QWIPs under high temperature ͑T͒ operation is the large dark current. Although many theoretical and experimental studies on the T effect on QWIP performances have been carried out, [5][6][7][8][9][10][11][12][13] the similar research in another promising detector named as superlattice infrared photodetectors ͑SLIPs͒ is deficient.…”

Temperature dependence of the photoresponse in two superlattice infrared photodetectors with different single barriers is studied. It is found that the short-wavelength response decreases with temperature, but the long-wavelength one increases. The crossing point of those two response ranges is independent of temperature. The movement of its associated wavelength under different biases is investigated and analyzed. The relevant physical mechanisms are found and integrated into a simple model to explain the experimental results. Based on the model, another sample with a superlattice integrated with multiple quantum wells is designed to demonstrate whether its temperature dependence of the photoresponse is consistent with our understanding. The sample indeed shows a broadband response which enhances with temperature in all wavelengths.

“…The upper surface of a finished CMOS chip is amorphous; epitaxy on such a surface will not lead to highquality monocrystalline material. The silicon crystal could be used as a template for epitaxy after etching through the interconnect stack [61], but the preference in VLSI processing for (1 0 0) oriented silicon complicates this approach (see, e.g. Ref.…”

The traditional microchip processes, stores and communicates electrical information. Here we review an emerging class of microchips that have additional functionality through extra integrated components in the chip. In the final manufacturing stage, layers are added on top of the chip, with a specific property such as sensitivity to ionizing radiation. This paper reviews the technology underlying these monolithic microsystems, including the incorporation of new materials, the unconventional application of photoresist layers, and lowtemperature technology for suspended membranes. The manufacturing of exemplary microsystems, such as the active pixel sensor and liquid-crystal-on-silicon, is detailed. A new class of fully integrated radiation imaging systems is now technologically within reach. r
