Abstract :
The use of thin high-bandgap ´spikes´ or thin low-bandgap ´dips´ inside conventional rectangular quantum wells gives supplementary flexibility in engineering intra- and inter-band energy level separation. The paper presents simulation and experimental studies of the effects of ´spikes´ and ´dips´ on the fundamental quantum well properties.
