Photoconductive Energy Gap Formula & Calculator

This calculator determines the photoconductive energy gap (Eg) of a semiconductor material using the formula: Eg = hc/λ

Where:

• Eg is the photoconductive energy gap in electron volts (eV)
• h is Planck’s constant (6.626 x 10^-34 J·s)
• c is the speed of light (3 x 10^8 m/s)
• λ is the wavelength of the incident light in meters (m)

Photoconductive Energy Gap Calculator

Example Calculation: Let’s say we have a semiconductor material that is illuminated with light of wavelength λ = 500 nm (which is 500 x 10^-9 m). We can calculate the photoconductive energy gap (Eg) using above calculator with constants h and c.

Input:

• Wavelength (λ): 500 nm

Output:

• Photoconductive Energy Gap (Eg): 2.48 eV

This means that the energy gap of the semiconductor material is 2.48 eV, which indicates the minimum energy required for an electron to transition from the valence band to the conduction band when illuminated with light of wavelength 500 nm.
