Abstract

fetched live from OpenAlex

A special CdZnTe (CZT) device on THM grown crystal has been developed. The device has different work function metals on opposite electrodes yet operates at room temperature like a conventional back-to-back symmetric MSM detector and not a one directional Schottky diode device. Aiming at creating a big breakthrough in CZT imaging device technology, the special CZT device presented in this study is capable of increasing the photopeak count by up to 50% compared to conventional CZT imaging device while maintaining good room temperature energy resolution by not significantly trading off detector leakage current. Pixel pad size and interpixel gap on a 20x20x5 mm3, 8x8 pixel pattern that result in optimum detector efficiency and interpixel resistance are presented. Sensitivity improvement impact on other device configuration will also be discussed. The design is highly practical, reliable and suitable for mass production.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
