A review of blue light emitting diodes for future solid state lighting and visible light communication applications

Progress of Reliability and Failure Mechanisms for GaN‐Based Light‐Emitting Diodes

“…GaN-based micro-LEDs, with a typical size of tens of microns, have drawn lots of attention because of many advantages for applications, such as high-efficient, flexible displays [94] and visible light communications. [95,96] However, the current densities used for these two applications are different. The display is normally operated under a small current region, but for light communications, the current density is generally above kA/cm 2 .…”

Study on Modulation Bandwidth of GaN-Based Micro-Light-Emitting Diodes by Adjusting Quantum Well Structure

“…Light-emitting diode (LED) has undergone great developments since its birth, penetrating every corner of our lives. Recently, great opportunities for LEDs are beginning to emerge in visible light communications (VLC) [ 1 , 2 ]. However, the major factor limiting the performance of GaN/InGaN LED-based VLC systems is the modulation bandwidth of the LEDs, which is far from the needs of modern wireless communication systems, creating an enormous obstacle to its application in VLC [ 3 , 4 ].…”

Understanding Indium Nitride Thin Film Growth Under ALD Conditions by Atomic Scale Modelling: From the Bulk to the In-Rich Layer

“…Light Emitting Diodes (LEDs) constitute a class of dispositives with large applicability in display lighting in electronic devices [1], such as mobile phones and computer screens, as well as in public lighting [1][2][3], horticulture [4] and medicine [1,5]. The basic principle of LEDs is the assembly of p-and n-doped semiconductors with holes and electrons acting as majority carriers, respectively [1,3,6].…”

“…Light Emitting Diodes (LEDs) constitute a class of dispositives with large applicability in display lighting in electronic devices [1], such as mobile phones and computer screens, as well as in public lighting [1][2][3], horticulture [4] and medicine [1,5]. The basic principle of LEDs is the assembly of p-and n-doped semiconductors with holes and electrons acting as majority carriers, respectively [1,3,6]. In close contact, the partial overlapping conduction band of these materials enables the diffusion of free electrons towards the p-doped semiconductor, which concentrate near the contact and promotes accumulation of holes in the n-doped part to form the depletion region [4].…”
