摘要: A 50×50μm pixel field emitter array image sensor with a highly sensitive avalanche-mode photoconductive target and scanning electron focusing system consisting of permanent magnets were fabricated tested as step toward the development ultrahigh-sensitivity compact sensors for high-definition television cameras. The experimental results revealed that magnetic conditions prototype in accordance those estimated from simulation, could obtain both enough resolution its size high sensitivity by electrons emitted onto target.
