Abstract
Various techniques may be employed for the excitation and control of micromechanical systems such as electrostatic or thermal transduction. However, most of these techniques require a dedicated driver circuit to provide the voltage or current levels needed for these actuators. On the other hand, the inefficiency of these techniques often necessitates the need for a local energy source. As such, options for remote operation of microactuators remain limited. Herein, we report on the first demonstration of direct optomechanical excitation of microstructures utilizing depletion region actuators. We demonstrate the possibility of using light to modulate the space charge density, and hence, the internal strain across the depletion region of regular p-n junctions. The modulation of strain across the junction can be effectively transformed into mechanical displacements. We show that the amount of force induced in the junction and the mechanical displacements can be controlled by varying the intensity of illumination. The produced strain does not scale when the device dimensions are reduced, making it a suitable actuation technique at nano-scales.

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.
