Definition

1. Noun (Physics/Electronics):
   • Photoconduction: The property of a material where its electrical conductivity increases when it is exposed to light. This is the primary and most common meaning of "quang dẫn".
   • Photoconductor: A material or device that exhibits photoconduction.

Usage Examples

• Noun:
  • Hiện tượng quang dẫn được ứng dụng trong nhiều cảm biến ánh sáng. (The phenomenon of photoconduction is applied in many light sensors.)
  • Chất bán dẫn này là một chất quang dẫn tốt. (This semiconductor is a good photoconductor.)
  • Độ quang dẫn của vật liệu thay đổi theo cường độ chiếu sáng. (The photoconductivity of the material changes with light intensity.)

Advanced Usage

• "hiệu ứng quang dẫn": photoconductive effect.

  • Máy photocopy hoạt động dựa trên hiệu ứng quang dẫn. (Photocopiers operate based on the photoconductive effect.)

• "tế bào quang dẫn": photoconductive cell.

  • Tế bào quang dẫn trong máy đo sáng đã bị hỏng. (The photoconductive cell in the light meter is broken.)

Variants and Related Words
