Numerical analysis of the non-cooled infrared sensors based on different thermoelectric materials
Calculation and optimization of parameters for thermoelectric sensors of infra-red radiation based on CdSb, InSb, Bi2Te3, antimony, and Bi-Sb alloys have been realized. Sensitivity, time constant, and noise equivalent power (NEP) of those sensors have been determined at different conditions....

| Sumario: | Calculation and optimization of parameters for thermoelectric sensors of infra-red
radiation based on CdSb, InSb, Bi2Te3, antimony, and Bi-Sb alloys have been realized.
Sensitivity, time constant, and noise equivalent power (NEP) of those sensors have been
determined at different conditions.
A comparative analysis of sensors based on wires or films has been made. Both
advantages and disadvantages of corresponding constructions have been discussed.
The obtained results have been compared with experimental data obtained in the
Academy of Sciences of Moldova (ASM) and literature data. This comparison has confirmed
a good quality and perspective of studied constructions. |
