"overcomes needing bulky/ complex cryogenics to offer high sensitivity, low noise, fast response, broadband, by using PbTe film/ CdTe/PbTe heterojunction semiconductors based on electromagnetically induced potential well effect... at heterojunction interface, channel with high carrier concentration, low scattering, high mobility formed spontaneously... less scattering, faster drift velocities, high carrier concentration/ mobility, lower recombination rates, enabling faster/ more efficient carrier collection"
