Theoretical analysis of the response time of MWIR InAs/InAsSb T2SL barrier detector

Dear Scientist!

This database contains data collected due to conducting study: "Theoretical analysis of the response time of MWIR InAs/InAsSb T2SL barrier detector" funded by National Science Centre Poland (Grant reference 2022/45/B/ST7/01393). 

The file structure results from the output data obtained by different measurement methods (current-voltage characteristics, spectral response measurements). Experimental data were compared with numerical simulations carried out using the commercial APSYS program. You can find a following folders and files:

1. Exp_Current-voltage (.opju) - Dark current density versus bias voltage for the n+BnN+ T2SL detector at 230 K and 300 K;
2. Exp_RdA (.opju) - Modulus of the dynamic resistance and the detector area product versus bias voltage for the n+BnN+ T2SL detector at 230 K and 300 K;
3. Cal_threshold_voltage (.xlsx) - Calculated dependence of Vfb and Vth on the barrier doping concentration;
4. Calc_I-V_and_RdA (.xlsx) - Calculated (APSYS) characteristics of the n+BnN+ T2SL detector at 300 K;
5. Calc_band_diagram_unbiased (.opju) - Calculated band diagram of the n+BnN+ T2SL detector at 230 K at a zero bias voltage;
6. Calc_band_diagram_biased (.opju) - Calculated band diagram of the n+BnN+ T2SL detector at 230 K at a -0.5 V voltage;
7. Calc_time_response_1 (.opju) - Calculated detector's response to a rectangular input signal of different durations, plotted on a linear scale;
8. Calc_time_response_2 (.opju) - Calculated detector's response to a rectangular input signal of different durations, plotted on a logarithmic scale.
9. Calc_diffusion_coefficient (.xlsx) - Calculated ambipolar diffusion coefficient relative to the diffusion coefficients for holes as a function of electron concentration;
10. Ambipolar diffusion coefficient formula (jpg)
