Institution: The City College of CUNY

Agency: Missile Defense Agency
Topic: BMDO97T002
Budget: 08/01/97 - 01/31/98

Quantum well structures in cubic materials show benefits from intentional strain, due to splitting of the valence band. In hexagonal materials, the valence band shows similar splitting, but without the strain. We believe that, by doing Substrate Bandgap Engineering, hexagonal heterostructures can be made, with strong potential benefits for blu...

Agency: Navy
Topic: N94-155
Budget: 03/28/95 - 09/27/95

Crystals of ZnSe are needed as substrate wafers for the growth of 11-VI epitaxial structures for blue and green LEDs and lasers. The matching of lattice constants, thermal expansion coefficients and energy bands, as well as chemical compatibility, provide a strong incentive to use native substrates. Classical growth methods all suffer from probl...

Zinc sulfide has long been known as an efficient scintillator: it was used in powder form by Rutherford for detection of alpha particles and continues to be used for that purpose. Under beta stimulation it is also superior: it is the universal blue phosphor of television screens. Powder scintillators, however, are unsatisfactory for gamma ray...

Budget: 01/01/91 - 12/31/91

HIGH TEMPERATURE SCINTILLATORS ARE NEEDED FOR GAMMA-RAY DETECTION IN BOREHOLE LOGGING. ZINC SULFIDE HAS LONG BEEN KNOWN AS A VERY EFFICIENT SCINTILLATOR; AS A THIN POWDER LAYER, IT IS CURRENTLY USED FOR -PARTICLE DETECTION. AS A LARGE TRANSPARENT BOULE, THIS COMPOUND WOULD ALSO BE USEFUL FOR GAMMA-RAY DETECTION. AN ECONOMICALTECHNIQUE FOR THE GR...
