An electromagnetic wave is 671 nm, and the intensity of light is 1 W/m^2. a) What is the wavelength? b) What is the frequency? c) What is the amplitude? What does a photon energy unit of a Joule equal? What is the wavelength (in meters) of a photon that has a frequency of ...
Heat and Light Intensity Influence on (I–V) Characterization of Cu2S Film/p-Si HeterojunctionI–V characteristics of Cu2S film/p-SiThermal evaporationCuprous sulphide was deposited on p-type silicon substrate by thermal evaporation techniques, to form a Cu2S film/p-Si heterojunction, and deposited...
Hole transport in transient photocurrent measurements for a-Si:H p-i-n structures has been investigated as a function of light intensity, bias voltage and temperature. One important result is that in comparison with electron transport, the space-charge-limited-current features do not appear, even...
This is the SI unit for luminous intensity. The definition relates to blackbody radiation emitted at a certain temperature for a certain material (so I...
Candela (cd).Unit of luminous intensity. The value of the candela is now based on the luminous efficacy of monochromatic radiation of frequency 540 × 1014Hz, which is 683 lm/W. Prior to 2018, the candela was the measure of electromagnetic radiation, in a specified direction, that had an...
I would suggest that ThreeJS officially adopt SI units for its physical variables including distance, time, mass, light intensity, etc. Right now ThreeJS is trying to be unit agnostic. While I can understand the motivation, it makes it harder to combine assets together in a ThreeJS scene -...
The flexible structure, high defined power, and resistance to the intensity of solar radiation have led CIGS solar cells to become progressively more used for space applications. CIGS PV solar cells have an extremely high absorption coefficient at the forbidden energy band gap of 1.5 eV, resulting...
