Mechanisms of Forward Current and Reverse Leakage Current in GaN-Based Blue Light Emitting Diodes

Applied Mechanics and Materials, 2013
By measuring the current-voltage (I-V) characteristics in the temperature range of 100 K to 300 K, mechanisms of the forward tunneling current and the reverse leakage current of GaN-based blue light emitting diodes are analyzed. For the forward current, both the temperature-independent current slope and an ideality factor larger than 2 are typical ...

Tunneling-Hopping Transport Model for Reverse Leakage Current in InGaN/GaN Blue Light-Emitting Diodes

IEEE Photonics Technology Letters, 2017
The nature of charge transport in GaN-based light-emitting diodes (LEDs) under reverse biases still remains elusive as the bias- and temperature-dependent characteristics of the current can hardly be formulated using a single transport mechanism. In this letter, based on numerical fitting, we develop a combined tunneling-hopping transport model to ...

Reduction of Light Leakage in Protruded Electrode by Refractive Index Matching Between Protrusion and Blue Phase Liquid Crystal

IEEE Photonic Society 24th Annual Meeting, 2011
We have studied the light leakage mechanism of the protruded electrode used for blue phase LCD. According to our study, the light leakage can be reduced by identical refractive indices of the protrusion and BPLC.

Detection of tissue expander leakage by methylene blue instillation: An effective method

2012
Background: Tissue expansion is an important and widely used technique of soft tissue reconstruction. Leakage of the expanders is one of the complications and it might at times be difficult to detect.Method and Conclusion: We used methylene blue stained saline for inflation of tissue expanders in 42 cases and found it to be an effective and simple ...
