Paper Abstract
Visible and solar blind UV detector arrays with spectrum below visible light or solar blind avoid
interference from visible light and solar radiation. A candidate for UV detectors is ZnO with a high
bandgap of 3.4 eV. ZnO with combinations of Mg or Cd can be tuned to absorb ultraviolet light from 210
nm to 450 nm. Banpil is developing visible and solar blind photodetectors using ZnO nanowires grown at
temperatures below 400C to facilitate direct ZnO growth on silicon ROICs providing maximum photon
absorption. Potential candidates to combine with ZnO to increase the bandgap potential are MgO and
BeO. Solution methods were developed to grow ZnBeO nanowires and solution methods to overcome
the ZnO wurtzite, MgO cubic and miscibility gap to grow ZnMgO nanowires. Modeling, simulation,
process steps to grow ZnBeO and ZnMgO using electrophoresis and final measurement results are shown
for generating ZnBeO and ZnMgO nanowire solar and visible blind sensors.
