Metal-based plasmonics has a wide range of important applications but is subject to several drawbacks. In this paper, we propose and investigate an all-semiconductor-based approach to plasmonics in mid-infrared (MIR) wavelength range using InAs heterostructures. Our results show that InAs heterostructures are ideal for plasmonics with the shortest plasmon wavelength among common semiconductors....
We extend three types of overloaded CDMA systems, by displacing in time the binary signature sequences of these systems: (1) random spreading (PN), (2) multiple-OCDMA (MO), and (3) PN/OCDMA (PN/O). For each of these systems, we determine the time shifts that minimize the overall multiuser interference power. The achievable channel load with coded and uncoded data is evaluated for the convention...
The performances of a pin versus a pn structure from GaInAsSb materials operating at room temperature are compared both from a theoretical point of view and experimentally. Theoretically, it is found in materials limited by generationrecombination currents, pn junctions have a higher D* than pin junctions. The thinner depletion region of pn junctions results in a lower responsivity but a higher...
The ionizing radiations are able to make either a permanent or temporarily damage in the electronic circuits. The temporary effects during irradiation can be used to detect the ionizing radiation. In this study a diode in reverse bias has been used to investigate the effects of ionization radiation on semiconductors. The variation of reverse current of diode has been monitored due to interactio...
Many animals depend on pheromone communication for successful mating. Sex pheromone in insects is usually released by females to attract males. In American cockroaches, the largest glomerulus (B-glomerulus) in the male antennal lobe (first-order olfactory center) processes the major component of sex pheromone. Using intracellular recordings combined with fine neuroanatomical techniques, we prov...
The concept of an imaging-type 3D spin detector, based on the combination spin-exchange interactions in ferromagnetic (FM) film and selectivity electron–photon conversion effect a semiconductor heterostructure, is proposed demonstrated model system. This novel multichannel idea direct transfer 2D spin-polarized electron distribution to image cathodoluminescence (CL). detector hybrid structure c...
We report on an exclusive and kinematically complete high-statistics measurement of the basic double-pionic fusion reaction pn→dπ(0)π(0) over the full energy region of the ABC effect, a pronounced low-mass enhancement in the ππ-invariant mass spectrum. The measurements, which cover also the transition region to the conventional t-channel ΔΔ process, were performed with the upgraded WASA detecto...
