Room-temperature electroluminescence is reported from InAsSb multiple-quantum-well light-emitting diodes. The diodes exhibited emission in the mid-infrared peaking near 4 m. The spectral dependence on injection current at 4 K was investigated and two transitions were identified, centered at 4.05 and 3.50 m, which are associated with the eigenstates of the(More)
Social loafing has effects on the performance of the teamwork in organization. This study aimed to examine the effects of member familiarity, task identifiability and perceived coworker loafing on the performance of teamwork in the organization. Then, proposed to test the interaction effects in member familiarity, task identifiability, and perceived(More)
The amplitudes of terahertz radiation are measured for a series of GaAs surface intrinsic-N(+) structures with various built-in surface electric fields as the bias. As the surface field is lower than the so-called "critical electric field" related with the energy difference between the Gamma to L valley of the semiconductor, the amplitude is proportional to(More)
