Abstract

fetched live from OpenAlex

Heterojunction diode and heterojunction photovoltaic cell structures are fabricated with (n+)a-Si/(i)a-Si and rf-sputtered indium-tin-oxide/Al films deposited on p-type crystalline Si using a plasma-enhanced chemical vapor deposition cluster tool system. Dark current–voltage characteristics of the heterojunction diodes are used to determine the carrier transport mechanisms. Experimental results showed the current is recombination-dominated at low forward bias (VA<0.25 V at 27 °C), multitunneling capture emission (MTCE)-dominated at medium bias (0.25<VA<0.45 at 27 °C), a combination of diffusion or thermionic emission and MTCE at high bias, and series resistance limited at very high bias ranges. Measurement results show that the boundary between each region is not fixed and is strongly dependent on temperature. High-frequency capacitance–voltage measurement has been used to extract band diagram parameters of the heterojunction diodes. Measured parameters, built-in potential, and conduction and valence band offsets, have been verified by Analysis of Microelectronic and Photonic Structures numerical device simulator. External quantum efficiency has been measured on photovoltaic cells and used for calculation of short-circuit current under AM1.5 illumination.

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.
