摘要：

Two types of direct electron detectors, potentially useful in low energy electron microscopy and photoemission electron microscopy (LEEM/PEEM) experiments, are reviewed in this paper. Hybrid pixel detectors, using a silicon sensor and based on Medipix2 offer a high detective quantum efficiency, due to an essentially noiseless readout, but are technically challenging. Backthinned monolithic active pixel sensors (MAPS) are not noise-free but have other advantages as discussed in this review.
