Normal incidence InAs/In0.15Ga0.85As dots-in-a-well (DWELL) detectors are reported in which the peak operating wavelength was tailored from 7.2 to 11 μm using heterostructure engineering of the DWELL structure. Using an optimized design, a detector

A number of remedial technologies are based on multiphase extraction, the simultaneous removal of contaminated liquids and vapors from soil or rock through one or more wells subjected to a high vacuum. This technical note proposes an empirical model

Vertical transport has been measured on GaAs/AlGaAs quantum-well superlattice infrared photodetectors in crossed electric and magnetic fields. The carriers, promoted by either thermal or photoexcitation from the doped ground state of the quantum well

We have observed a threshold voltage, below which no photocurrent flows, in a class of midwave quantum-well infrared photodetectors using (In,Ga)As/(In,Al)As lattice matched to InP substrates. We propose that this threshold voltage is the result of i

Electron transitions in the IR range, which correspond to transitions in the narrow bandgap semiconductors, are also realized in quantum‐dot structures. Quantum‐dot optoelectronic devices, which can replace devices based on narrow bandgap semicon

We have demonstrated an infrared photodetector based on intersubband transitions in doped (In, Ga)As quantum wells in which the excited state is confined by the minigap between two minibands in a surrounding superlattice. Sharp peaks were observed at

We present a simple, general method for calculating the binding energies of excitons in quantum-confined structures. The binding energy is given by an integral (over the electron and hole coordinates perpendicular to the confining layers) of a prescr

We have examined the patterns of expression of the homeotic gene Ubx in imaginal discs of Drosophila larvae carrying mutations in the abx, bx and pbx regulatory domains. In haltere discs, all five bx insertion mutations examined led to a general redu
