p-Type InN nanowires: towards ultrahigh speed nanoelectronics and nanophotonics
Bibliographic record
Abstract
In this paper, we demonstrate that p-type InN nanowires can be realized by direct magnesium (Mg) doping. X-ray photoelectron spectroscopy experiments on the sidewalls of Mg-doped InN nanowires indicate no surface electron accumulation with the background electron concentration below 1×10<sup>16</sup> cm<sup>-3</sup>. The presence of Mg-acceptors is clearly observed by the low-temperature photoluminescence (PL) spectroscopy, which shows a band-to-band recombination PL peak and a Mg-acceptor energy level related PL peak. The peak energy separation is about 60 meV, which is consistent with the Mg activation energy in InN. Single nanowire field-effect transistors are further fabricated and investigated, which clearly exhibits a p-type transistor behavior, representing the first direct evidence for p-type conduction in any InN structures. The potential device applications based on InN nanowires are also discussed.

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.
