Optical spectra and structure of CdP4 nanoclusters fabricated by incorporation into zeolite and laser ablation
O. A. Yeshchenko, I. M. Dmitruk, S. V. Koryakov +1
CdP4 nanoclusters were fabricated by incorporation into the pores of zeolite Na-X and by deposition of the clusters onto a quartz substrate using laser ablation-evaporation techniq…
Optical properties of CdP2 and CdP4 nanoparticles incorporated into Na-X zeolite matrix
O. A. Yeshchenko, I. M. Dmitruk, S. V. Koryakov +1
For the first time nanoparticles of CdP2 and CdP4 semiconductors were prepared and studied. The nanoparticles were prepared by incorporation into zeolite Na-X matrix. Absorption an…
Energy bands and Wannier-Mott excitons in Zn(P_{1-x}As_{x})_{2} and Zn_{1-x}Cd_{x}P_{2} crystals
O. A. Yeshchenko, M. M. Biliy, Z. Z. Yanchuk
Excitonic absorption, reflection and photoluminescence spectra of mixed Zn(P_{1-x}As_{x})_{2}crystals over the full range of x (0 < x < 1) and Zn_{1-x}Cd_{x}P_{2} crystals at 0 < x…
Biexcitonic Liquid in -ZnP Crystal: Quantum Bose Liquid and its Possible Superfluidity
I. S. Gorban, O. A. Yeshchenko, I. M. Dmitruk +1
A phonon-roton dispersion relation is proposed for the elementary excitations of a quantum biexcitonic liquid in semiconductors. The proposed dispersion relation is used as a start…
Comment on ``Inverse exciton series in the optical decay of an excitonic molecule''
I. S. Gorban, M. M. Bilyi, I. M. Dmitruk +1
Tokunaga et al. [Phys. Rev. B Vol. 59, R7837 (1999)] claim the first successful observation of the inverse exciton M series in the emission spectrum of excitonic molecules. We asse…
