FUNDAMENTAL CONTRIBUTION TO KNOWLEDGE
SCIENTIFIC PREDICTION: THE FIRST TO PROPOSE THE USE OF SUPERLATTICE AS:

* Efficient Thermoelement
* High Frequency Maser
* Phonon Filter

THE FIRST TO PREDICT THAT
# The current-voltage characteristic of superlattice should show at strong static fields an exponential rise of current due to ionization of impurities.
# In the low frequency region application of a c field results in a shift of the maximum of the current voltage curve towards larger voltages in superlattices.
