A Review of Transient Characterization Techniques for Quantum Dot Light‐Emitting Diodes

open access: yesAdvanced Physics Research, EarlyView.
This review surveys transient characterization techniques for quantum dot light‐emitting diodes, including TRPL, TREL, TA, and E‐TA. These methods resolve carrier‐selective dynamics across multiple time scales, enabling direct analysis of charge injection, exciton formation and recombination, efficiency roll‐off, and device degradation.

DNA electrophoresis studied with the cage model [PDF]

open access: yes, 2001
The cage model for polymer reptation, proposed by Evans and Edwards, and its recent extension to model DNA electrophoresis, are studied by numerically exact computation of the drift velocities for polymers with a length L of up to 15 monomers.

Expansion formulas for terminating balanced 4F3-series from the Biedenharn–Elliot identity for su(1,1) [PDF]

open access: yes, 2004
In a recent paper, George Gasper (Contemp. Math. 254 (2000) 187) proved some expansion formulas for terminating balanced hypergeometric series of type 4F3 with unit argument. In this article we show how one easily derives such expansion formulas from the
