Near-Field Emission of Lead-Sulfide-Selenide Homojunction Lasers
نویسنده
چکیده
A bstruct-Measurements of the near-field intensity dis ributions of .7 three lead-sulfide-selenide diode lasers operating near 4.8 pm have been made as a function of injection current. Localized emission in the near field exhibits peaked structure of full width from 5 to 10 pm for operation above threshold. From the dependence of the emission profiles on injection current estimates of 25 cm-I and 0.09 cm/A are E .4-made for the distributed loss and gain coefficients for one of the lasers. Optical confinement perpendicular to the p-n junction can be explained in terms of the homojunction properties. .2 ~2.0 .6

Gate-dependent carrier diffusion length in lead selenide quantum dot field-effect transistors.
We report a scanning photocurrent microscopy (SPCM) study of colloidal lead selenide (PbSe) quantum dot (QD) thin film field-effect transistors (FETs). PbSe QDs are chemically treated with sodium sulfide (Na2S) and coated with amorphous alumina (a-Al2O3) by atomic layer deposition (ALD) to obtain high mobility, air-stable FETs with a strongly gate-dependent conductivity. SPCM reveals a long pho...
متن کاملSynthesis and characterization of luminescent cadmium selenide/zinc selenide/zinc sulfide cholinomimetic quantum dots.
Luminescent quantum dots conjugated with highly selective molecular recognition ligands are widely used for targeting and imaging biological structures. In this paper, water soluble cholinomimetic cadmium selenide (core), zinc selenide/zinc sulfide (shell) quantum dots were synthesized for targeting cholinergic sites. Cholinomimetic specificity was incorporated by conjugation of the quantum dot...
متن کاملQuantum Maxwell-Bloch equations for spatially inhomogeneous semiconductor lasers
We present quantum Maxwell-Bloch equations ~QMBE! for spatially inhomogeneous semiconductor laser devices. The QMBE are derived from fully quantum mechanical operator dynamics describing the interaction of the light field with the quantum states of the electrons and the holes near the band gap. By taking into account field-field correlations and field-dipole correlations, the QMBE include quant...
متن کاملDark current analysis of Si homojunction interfacial work function internal photoemission far-infrared detectors
A detailed theoretical investigation of dark current mechanisms is performed for a novel Si n-i homojunction interfacial work function internal photoemission ~HIWIP! far-infrared ~FIR! detector. Thermionic emission, thermionic field emission and field emission currents, including the image force effect, are calculated and compared as functions of bias voltage and temperature. The bias and tempe...
متن کاملLow-threshold ZnO random lasing in a homojunction diode with embedded double heterostructure
An electrically pumped random laser diode was fabricated with a MgZnO/ZnO/MgZnO double heterostructure embedded in a ZnO pn junction. Gain can be achieved at very low-threshold current owing to exciton processes. Light closed loops are formed by random multiple scattering on vertical column boundaries in the thin film. The tilted and rough mesa edge planes serve as refraction mirrors, giving ri...
