I'm reading a technical lab report which study the effect of light and temperature on a silicon wafer. However i'm a bit confused if ambient condition in this case means.

Task 3, Investigate the influence of ambient conditions on the diode characteristics In this task both the silicon wafer and the SiC piece should be utilized. Perform reverse IV sweeps in dark and under illumination. (For the silicon wafer these measurements could be combined with Task 1). Perform measurements at room temperature and at least one selected elevated temperature, focus on the forward characteristics.

  • Is this means the effect of light on a piece of silicon?
  • or is it the effect of temperature?
  • or is it means the effect of both light and temperature on a piece of silicon?
  • Please provide the whole sentence or a paragraph. It's always hard to tell the exact meaning without context. – CowperKettle Feb 26 '19 at 16:31
  • Ambient conditions typically include temperature, humidity and air pressure. You haven't given the exact full context, but in a "technical lab report" it probably means those three (and possibly other) aspects of the environment are typical (not especially dark, humid, hot, noisy, windy, whatever). Effectively, ambient = surrounding environment, as shared by technicians and the thing being tested (which isn't hermetically sealed from the overall environment of the testing procedure). – FumbleFingers Feb 26 '19 at 16:33
  • Ambient probably means the laboratory conditions, before applying artificial conditions to the test sample. The test would make a study of the effect of varying both temperature and light in a controlled way. – Weather Vane Feb 26 '19 at 16:35
  • The question edit includes "Perform measurements at room temperature". This is the ambient condition. – Weather Vane Feb 26 '19 at 16:43

Ambient conditions are the general environmental conditions in an area. It is related to the word ambience. Thus it would certainly include temperature, and may include light if that's a particularly relevant environmental condition. It could also be humidity, air pressure, air movement, presence of dust, and so on.
