We have used both optical and electrical measurements to determine the trap density in InSb/InAlSb nonequilibrium detector structures. Both of these techniques result in very good agreement with trap densities of 5 x 10(14) cm(-3).}, year = {2000}, journal = {Journal of Physics-Condensed Matter}, volume = {12}, number = {50}, pages = {L731-L734}, month = {Dec 18}, isbn = {0953-8984}, doi = {10.1088/0953-8984/12/50/101}, language = {eng}, }
