“…Additionally, the tunneling effect, such as indicated in the band-to-band model, is implemented in the continuity equations as additional generation-recombination processes. [6][7][8] These models are used to describe the motion of carriers. In the simulation, the only change effected is the geometric parameters of the device.…”

In this work, three designs of spherical refractive microlenses have been investigated. The simulation results show that the response and crosstalk of photodetectors with silicon microlenses are one order of magnitude better than for photodetectors with InSb microlenses or silicon thin-film microlenses. Additionally, we determined the optimum position for the focused beam as a function of the radius of curvature of the microlenses. This optimum position is dependent only on the absorption characteristics of the InSb material.

“…Spectral crosstalk existing between two bands can influence the function of discrimination. It will be effectively suppressed by incorporating a compositional barrier between two absorption layers [6]. In this paper, the barrier composition and thickness is optimized according to practical technical parameters.…”

Spectral crosstalk suppressing design of simultaneous two-color HgCdTe medium-wave/long-wave (MW/LW) infrared n-p-p-n detector is carried out, using commercial Technology Computer Aided Design ( TCAD ) software Apsys. A compositional barrier between two absorption layers is introduced and designed to suppress spectral crosstalk. MW-to-LW crosstalk can be notably suppressed to 2.1% while LW-to-MW crosstalk can be maintained less than 1%.
