Effect of Organic Contamination on the Electrical Degradation of Hydrogen-Terminated Silicon upon Exposure to Air under Ambient Conditions
Bibliographic record
Abstract
The degradation of the electrical characteristics of hydrogen-terminated silicon (both n- and p-doped) under typical laboratory environments was investigated. When a hydrogen-terminated silicon (H-Si) surface was exposed to air under ambient conditions, the current density/bias voltage (J-V) curve of the mercury-silicon junction thus formed changed significantly during the first 50 h. For n-type H-Si surfaces, the J-V curve initially maintained ohmic characteristics for a period of 8-12 h, then evolved to diode behavior; for p-doped samples, the current density showed a rapid increase and reached a maximum in about 20 h. In both cases, the electrical property was recovered to some extent after sonication in organic solvents. In agreement with infrared spectroscopic results, organic contamination upon exposure to ambient air is suggested to play an important role in the change of the electrical performance of hydrogen-terminated silicon. © 2003 The Electrochemical Society.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
