Disruptive and reactive interface formation of molybdenum trioxide on organometal trihalide perovskite
Bibliographic record
Abstract
X-ray and ultra-violet photoemission spectroscopies (XPS and UPS) are used to elucidate the physical, chemical, and electronic properties of MAPbI3/MoO3 interface. The XPS data suggest migration of iodide species from the MAPbI3 into the MoO3 upon direct contact of these two layers. Chemically, these iodide inclusions cause a significant presence in reduced Mox+ species. Electronically, UPS data show that this reaction induces gap states and reduces the MoO3 workfunction. It is shown that a thin organic interlayer blocks migration of volatile iodide from MAPbI3 into the MoO3. This organic buffer layer results in significantly better chemical stability, reduced gap state density, and higher MoO3 workfunction. These results highlight the importance of organic buffer layers in separating these two materials during device fabrication.

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.
