The currently ubiquitous light-emitting diodes (LEDs) have revolutionized the lighting
industry. Contrary to common belief, however, LEDs are much more than just simple …

In conventional photon-based heat transfer, one typically assumes that the chemical
potential of photons is zero. On the other hand, when a semiconductor is under external …

Recovering ubiquitous low grade waste heat can lower the amount of global net energy
generation required and would thereby support the transition to renewable energy sources …

Fundamental thermodynamic considerations reveal that efficient emission from an
electrically injected light emitting diode (LED) can lead to the cooling of the device. This …

Recent advances in the photoluminescent cooling of doped glasses provoke the question of
whether similar progress is possible in electroluminescent cooling (ELC), and if so, what are …

High performance infrared light emitting diodes (LEDs) have drawn wide attention because
of their significant applications in biomedicine, agriculture, aquaculture, night vision security …

Recent studies of electroluminescent cooling (ELC) in III-V structures demonstrate the need
to better understand the factors affecting the efficiency of light emission and energy transport …

We propose a multijunction configuration for an electroluminescent cooling system,
incorporating multiple semiconductor layers with different band gaps. Through theoretical …

Current crowding close to electrical contacts is a common challenge in all optoelectronic
devices containing thin current spreading layers (CSLs). We analyze the effects of current …

The recently proposed diffusion-driven charge transport (DDCT) method can allow a
paradigm shift in the design of optoelectronic devices, by changing both the current injection …
