ABSTRACT:
Apparatus for detecting the presence of a gas in an ambient atmosphere comprises a multiple quantum well structure; a thin layer of a transition metal formed on the multiple quantum well structure; and an arrangement for monitoring the transmission of electromagnetic radiation sent through the multiple quantum well structure and reflected back therethrough by the thin layer.
