Abstract

Vibrational spectra of gas-source molecular beam epitaxy grown dilute InN{sub x}As{sub 1-x}/InP (001) alloys are obtained using a Fourier-transform infrared (IR) spectroscopy. A triply degenerate N{sub As} local vibrational mode of T{sub d}-symmetry is observed near 438 cm{sup -1} corresponding to the In-N bond energy. The analysis of composition dependent infrared reflectivity spectra in InNAs has predicted a two-phonon-mode behavior. In In(Ga)-rich GaInNAs alloys the observed splitting of the N{sub As} local mode into a doublet for the N{sub As}-Ga{sub 1}(In{sub 1})In{sub 3}(Ga{sub 3}) pair-defect of C{sub 3v}-symmetry is consistent with our simulated results based on a sophisticated Green's function theory.

Initial exploration of growth of InN by electrochemical solution growth.

Technical Report Waldrip, Karen

This report summarizes a brief and unsuccessful attempt to grow indium nitride via the electrochemical solution growth method and a modification thereof. Described in this report is a brief effort using a $50,000 LDRD award to explore the possibilities of applying the Electrochemical Solution Growth (ESG) technique to the growth of indium nitride (InN). The ability to grow bulk InN would be exciting from a scientific perspective, and a commercial incentive lies in the potential of extending the ESG technique to grow homogeneous, bulk alloys of In{sub x}Ga{sub 1-x}N for light emitting diodes (LEDs) operating in the green region ofmore »« less

Synthesis of InN{sub x}P{sub 1-x} thin films by N ion implantation

Journal Article Yu, K; Walukiewicz, W; Wu, J; ... - Applied Physics Letters

Dilute InN{sub x}P{sub 1-x} alloy thin films were synthesized by nitrogen ion implantation into InP using doses corresponding to N mole fraction up to 0.048. In the films with the highest N contents, it was shown using modulated photoreflectance that the fundamental band gap energy was decreased by up to 180 meV. The band gap reduction is similar in magnitude to that observed in epitaxially grown III--N{sub x}V{sub 1-x} alloys. The InN{sub x}P{sub 1-x} layers were thermally stable up to an annealing temperature of 850{sup o}C. Using the recently developed band anticrossing model which relates the band gap reduction tomore »« less

Bond-length strain in buried Ga{sub 1{minus}x}In{sub x}As thin-alloy films grown coherently on InP(001)

Journal Article Woicik, J; Gupta, J; Watkins, S; ... - Applied Physics Letters

The bond lengths in a series of strained, buried Ga{sub 1{minus}x}In{sub x}As thin-alloy films grown coherently on InP(001) have been determined by high-resolution extended x-ray absorption fine-structure measurements. Comparison with a random-cluster calculation demonstrates that the external in-plane epitaxial strain imposed by pseudomorphic growth opposes the natural bond-length distortions due to alloying.{copyright} {ital 1998 American Institute of Physics.}

Infrared photodissociation spectroscopy of Ag{sub n}(C{sub 6}H{sub 6}){sub m} and Ag{sub n}(C{sub 6}D{sub 6}){sub m} clusters: Evidence of adsorption-induced symmetry reduction in benzene

Technical Report Koretsky, G; Knickelbein, M

Photodepletion spectroscopy has emerged in recent years as a powerful tool for probing the optical response of both neutral and charged metal clusters. Comparison of measured spectra with theoretical predictions has allowed for inferences about size-specific cluster structures. The vibrations of benzene-h{sub 6} and benzene-d{sub 6} on single crystal metal surfaces have been thoroughly investigated using a number surface science technique. On silver surfaces, it has been found that benzene adsorbs weakly, with vibrational frequencies that are shifted downward by approximately 5 cm{sup {minus}1} relative to those of gas-phase benzene. Furthermore, modes which are inactive for gas-phase benzene are seenmore »« less

Extended wavelength mid-infrared photoluminescence from type-I InAsN and InGaAsN dilute nitride quantum wells grown on InP

Journal Article Wheatley, R.; Marshall, A.; Zhuang, Q.; ... - Applied Physics Letters

Extended wavelength photoluminescence emission within the technologically important 2–5 μm spectral range has been demonstrated from InAs{sub 1−x}N{sub x} and In{sub 1−y}Ga{sub y}As{sub 1−x}N{sub x} type I quantum wells grown onto InP. Samples containing N ∼ 1% and 2% exhibited 4 K photoluminescence emission at 2.0 and 2.7 μm, respectively. The emission wavelength was extended out to 2.9 μm (3.3 μm at 300 K) using a metamorphic buffer layer to accommodate the lattice mismatch. The quantum wells were grown by molecular beam epitaxy and found to be of a high structural perfection as evidenced in the high resolution x-ray diffraction measurements. The photoluminescence was more intensemore »« less
