Intersubband absorption in coupled GaN/AlGaN double quantum wells (DQWs) has been measured.

Intersubband optical absorption in narrow, 15-30 Angstrom wide, GaN/AlGaN quantum wells has been measured.

A new technique is reported which allows the observation of intersubband spontaneous emission in unipolar quantum cascade lasers above threshold.

It is shown that semiconductor lasers utilizing intersubband transitions in quantum boxes, so-called intersubband quantum-hox (IQB) lasers,can have significantly lower threshold current densities a

Linear least-squares models are often used to describe how an endogenous variable depends on some exogenous variables and to make forecasts based on that description.

The general area of the paper is methods and data structures to efficiently avoid data duplication.

Let , is less probable than, be a comparative probability relation on the algebra A of all subsets of a finite set S.
