recommendations! Published in 2020 at "Semiconductor Science and Technology"

DOI: 10.1088/1361-6641/abd045

Abstract: III-nitride semiconductors with a cubic crystal structure have shown promise in enhancing efficiency in photonic and optoelectronic applications. The recent interest in cubic III-nitrides has arisen due to the inability to realize enhanced efficiency in… read more here.

DOI: 10.1088/1751-8121/ad8a2f

Abstract: In this paper we consider two dimensional quantum system with an infinite waveguide of the width d and a transversally invariant profile. Furthermore, we assume that at a distant ρ there is a perturbation defined… read more here.

DOI: 10.1093/ptep/ptz006

Abstract: Standard calculations by Fermi's golden rule involve approximations. These approximations could lead to deviations from the predictions of the standard model, as discussed in another paper. In this paper we propose experimental searches for such… read more here.

DOI: 10.1103/physrevlett.129.140402

Abstract: Fermi's golden rule applies in the limit where an initial quantum state is weakly coupled to a continuum of other final states overlapping its energy. Here we investigate what happens away from this limit, where… read more here.
