Interactive Visualization of Diode Physics: Bridging the Fidelity‐Accessibility Gap in Web‐Based Engineering Education

Computer Applications in Engineering Education, Volume 34, Issue 3, May 2026.
ABSTRACT In engineering education, a “fidelity‐accessibility trade‐off” persists: accessible web simulations often lack physical accuracy, while complex industrial tools impose heavy cognitive loads. This hinders effective instruction in semiconductor physics in remote, hardware‐constrained environments.
