Low dark current (210 nA/cm2 at −1 V), high shunt resistance area product (0.3 MΩ cm2) photodetector arrays have been fabricated on 100 mm diameter InGaAs/InP epitaxial wafers. The lattice-matched In.53Ga.47As was deposited by organometallic vapor

Photoluminescence spectra and efficiency have been measured for several strained InAsyP1−yInxGa1−xAs (0.28 < y ≤ 0.62; 0.66 ≤ x ≤ 0.83) double heterostructures grown by vapor phase epitaxy on InP substrates with graded InAsP buffer layers.

We describe an ESR study of pure and irradiated TTF-TCNQ in the low temperature range (1. 2 K − 4. 2 K) where nonlinear transport has been observed. We find no evidence of an activated term in the susceptibility; our results yield an upper limit of

We report on recent results in using InGaAs/InP focal plane arrays for visible light imaging. We have fabricated substrate-removed backside illuminated InGaAs/InP focal plane arrays down to a 10 μm pitch with high quantum efficiency from 0.4 μm thr

We describe innovations in short wave infrared (SWIR) InGaAs focal plane arrays and cameras which now allow imaging under starlight only conditions at video rates. These lattice matched In.53Ga.47As imagers detect 0.9 μm to 1.7 μm SWIR band light,

A 32 /spl times/ 32 element InGaAs focal plane array was demonstrated. These arrays may find application in 3-dimensional imaging systems. APD arrays will be advantageous in these systems since the bandwidths required of the readout integrated circui
