Quantum and transport lifetimes of a two‐dimensional hole gas in the presence of spin–orbit interaction
Bibliographic record
Abstract
Abstract We present a simple theoretical approach for evaluating the spin‐dependent carrier distribution as well as quantum and transport lifetimes in a two‐dimensional hole gas (2DHG) in the presence of spin–orbit interaction (SOI) induced by the Rashba effect. For low temperatures and over a wide range of the sample parameters, the SOI can enhance the mobility of the sample system and the quantum and transport lifetimes of a 2DHG due to background‐impurity scattering do not differ significantly between different spin branches. These are mainly due to the unique features of the hole‐impurity scattering in the presence of the SOI. A small difference of the quantum lifetimes in different spin branches has been observed experimentally in spin‐split two‐dimensional electron gas systems. Our results indicate that this interesting observation can be made in spin‐split 2DHGs as well. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

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.
