Query: Infrared detector based on conduction band intersubband transitions in a
  heterojunction between two quantum wires   In this paper we study the feasibility of an infrared detector based on
intersubband transitions in the conduction band of the junction between two
semiconductor quantum wires. We show that by varying the radius of the wires it
is possible to engineer a band structure of the junction that would be
favorable for creating and detecting photocurrent. The suggested concept also
allows for broadband detection based on arrays of wires with different radii.
