D.C. electrical and optical properties of vacuum-deposited organic semiconductor FePcCl thin films
Bibliographic record
Abstract
Sandwich and planar structures are fabricated by a vacuum deposition method using iron phthalocyanine chloride (FePcCl) as an active layer and gold (Au) as electrodes. The permittivity ε of FePcCl is determined from the dependence of capacitance on film thickness. The current density voltage characteristics characteristics of the Au/FePcCl/Au structure at room temperature are found. Thermally generated hole concentration p0, hole mobility µp, total trap concentration Nt, and depth of the trap level are estimated. The activation energies of FePcCl films are determined from Arrhenious plots of ln σ versus 1000/T. The absorption and reflectance spectra of a FePcCl thin film deposited at room temperature are recorded in the spectral range 300900 nm. The optical band gap of a FePcCl thin film is determined from the α2 versus hν graph. The optical constants n and k are found. The real and imaginary parts of the optical dielectric constant ε1 and ε2 are calculated. These optical parameters are plotted against photonenergy. PACS Nos.: 72.80.Le, 73., 78.20.e

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
