Carrier leakage in blue‐green II–VI semiconductor lasers

Applied Physics Letters, 1995
Carrier confinement in blue-green II–VI semiconductor lasers was investigated. For devices longer than 300 μm an energy barrier of 260–280 meV was found to confine the electrons, the carrier being mainly responsible for leakage, within the active region.

An evaluation of the effect of methylene blue dye pH on apical leakage

Journal of Endodontics, 1993
The effect of varying the pH of 2% methylene blue dye on apical leakage was evaluated. Eighty-four roots of extracted human teeth were used in this study. The roots were endodontically cleaned and shaped, obturated, apically resected, and amalgam or Temporary Endodontic Restorative Material retro-fillings were placed. The roots were immersed for 7 days

Quantifying blood-brain-barrier leakage using a combination of evans blue and high molecular weight FITC-Dextran

Journal of Neuroscience Methods, 2019
Evans blue (EB) is the most widely used tracer to assess BBB leakage. However, a well-established method to obtain visualized and quantitative results of EB extravasation is presently unavailable.We reported a novel method to quantify BBB leakage by combining EB and high molecular weight FITC-Dextran (2000 kDa).

Exceeding 10 000 h of Lifetime in Blue Fluorescent Organic Light‐Emitting Diodes by Introducing an Electron Leakage Pathway

Advanced Optical Materials, 2023
Electron leakage is one of the most critical factors for the degradation of blue fluorescent organic light‐emitting diodes (FOLEDs), as it occurs when electrons injected from the cathode flow to an electron‐blocking layer (EBL) without being entirely consumed within an emissive layer (EML). To address this issue, this study introduces the concept of an
