Abstract
Band discontinuity is an important parameter for the design of heterojunction based electronic and opto-electronic devices. An alternative method for band offset measurement in quantum wells has been outlined in this paper. The band offset is determined from a comparison of experimental results and theoretical computations of the temperature dependent total charge content of a quantum well. In spite of the simplicity of the measurement procedures the result at its best has an error around ±2%.
