Abstract
An array of 812 gated Si field emitters arranged in a circular pattern with a diameter of 0.089 cm is used to bombard a 2.25 mu m thick, 220 mu m*460 mu m AlGaAs single-quantum-well, separate confinement heterostructure (SQW SCH) slab. Some of the emitted light is collected with a 50 mu m diameter core, multimode fiber that is positioned in close vicinity to the slab. With an excitation power of about 1.5 W cm-2 (10 kV acceleration), a 1 s electron exposure time, and a duty cycle of 0.1 Hz, the room temperature wavelength of the dominant peak in the emission spectrum is 7987 AA, which corresponds to the lowest-energy electron-hole transition (E1-E hh1) in the quantum well.
