Biaxial Strain Modulated Valence Band Engineering in III-V Digital Alloys
Sheikh Z. Ahmed, Yaohua Tan, Jiyuan Zheng +2
Some III-V digital alloy avalanche photodiodes exhibit low excess noise. These alloys have low hole ionization coefficients due to presence of small 'minigaps', enhanced effective…
Atomistic transport modeling, design principles and empirical rules for Low Noise III-V Digital Alloy Avalanche Photodiodes
Sheikh Z. Ahmed, Yaohua Tan, Jiyuan Zheng +2
A series of III-V ternary and quarternary digital alloy avalanche photodiodes (APDs) have recently been seen to exhibit very low excess noise. Using band inversion of an environmen…
Simple Formulas for Output Interception Power Estimation of Uni-Traveling Carrier Photodiodes
Keye Sun, Junyi Gao, Yuan Yuan +2
Simple analytical expressions for estimation of second order output intercept point (OIP2) and third order output intercept point (OIP3) of surface normal uni-traveling carrier (UT…
Characterization of band offsets in AlInAsSb alloys with varying Al composition
Jiyuan Zheng, Andrew H. Jones, Yaohua Tan +7
The unprecedented wide bandgap tunability (~1 eV) of AlInAsSb latticed-matched to GaSb enables the fabrication of photodetectors over a wide range from near…
Full band Monte Carlo simulation of AlInAsSb digital alloys
Jiyuan Zheng, Sheikh Z. Ahmed, Yuan Yuan +7
Avalanche photodiodes fabricated from AlInAsSb grown as a digital alloy exhibit low excess noise. In this paper, we investigate the band structure-related mechanisms that influence…
Dynamic-quenching of a single-photon avalanche photodetector using an adaptive resistive switch
Jiyuan Zheng, Cheng Ji, Xingjun Xue +7
One of the most common approaches for quenching single-photon avalanche diodes is to use a passive resistor in series with it. A drawback of this approach has been the limited reco…
