Abstract

fetched live from OpenAlex

Tin oxide nanowires (NWs) exhibit interesting electronic properties, which can be harnessed for applications in nanoelectronic devices and sensors. Oriented single crystalline tin oxide NWs were grown at 45 degrees from a titanium dioxide substrate. Their elastic properties were investigated in a two-point geometry using an atomic force microscope (AFM) coupled with a scanning electron microscope under ultrahigh vacuum conditions. Young's modulus was calculated by bending individual NWs and measuring the force exerted on the AFM tip during force-displacement measurements. For the NWs investigated, having radial dimensions below 45 nm and length up to 1.2 microm, we found an average value of 100 +/- 20 GPa, which is below the theoretical predictions calculated for different SnO(2) single crystal orientations, yet consistent with the indentation moduli of nanobelts. Finally, we discuss the effects of the nanowire-cantilever configuration on the measured Young's modulus.

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.
