Hot Phonon Bottlenecks and the Role of Non-Equilibrium Acoustic Phonons in III-V Multi-Quantum Well Systems

Izak Baranowski, Dragica Vasileska, Ian R. Sellers +1

The hot phonon bottleneck effect is a promising mechanism for the realization of a true hot carrier solar cell. Prior work has assumed that the acoustic phonons created via decay o…

Hydrogen-induced degradation dynamics in silicon heterojunction solar cells via machine learning

Andrew Diggs, Zitong Zhao, Reza Vatan +5

Among silicon-based solar cells, heterojunction cells hold the world efficiency record. However, their market acceptance is hindered by an initial 0.5\% per year degradation of the…

Low-Frequency Electronic Noise in the Aluminum Gallium Oxide Schottky Barrier Diodes

Subhajit Ghosh, Dinusha Herath Mudiyanselage, Sergey Rumyantsev +5

We report on the low-frequency electronic noise in (AlGa)O Schottky barrier diodes. The noise spectral density reveals 1/f dependence, characteristic of the fli…

The Role of Nonequilibrium LO Phonons, Pauli Exclusion, and Intervalley Pathways on the Relaxation of Hot Carriers in InGaAs Multi-Quantum-Well Structures

Yongjie Zou, Hamidreza Esmaielpour, Daniel Suchet +2

Under continuous-wave laser excitation in an InGaAs multi-quantum-well (MQW) structure, the carrier temperature extracted from photoluminescence rises faster for 405 nm excitation…

Excess Noise in High-Current Diamond Diodes -- Physical Mechanisms and Implications for Reliability Assessment

Subhajit Ghosh, Harshad Surdi, Fariborz Kargar +5

We report results of an investigation of low-frequency excess noise in high-current diamond diodes. It was found that the electronic excess noise of the diamond diodes is dominated…
