Organic Permeable Base Transistors—Reliable Large‐Scale Anodization for High Frequency Devices

Advanced Functional Materials, EarlyView.
Electrochemical anodization is optimized for organic permeable base transistors (OPBTs), achieving an unprecedented 87% yield and reproducibility for vertical organic transistors (VOTs) on a 15 x 15 cm wafer. Controlled Al base oxidation ensures a median transconductance of 10−3 S, leakage current below 10−9 A, current gain of 106, and transit ...

Monolithically integrated circuits for Optical injection locking of ring lasers with QKD and QPSK applications [PDF]

arXiv, 2023
Optical injection locking of integrated ring lasers promises to be a key technology of the future, but it is still lacking experimental verification. In this paper we present two monolithically integrated photonic circuits that experimentally realize Optically injection locking of ring lasers.

Indistinguishable photons from deterministically integrated single quantum dots in heterogeneous GaAs/Si$_3$N$_4$ quantum photonic circuits [PDF]

Nano Letters, published online (2019), 2019
Silicon photonics enables scaling of quantum photonic systems by allowing the creation of extensive, low-loss, reconfigurable networks linking various functional on-chip elements. Inclusion of single quantum emitters onto photonic circuits, acting as on-demand sources of indistinguishable photons or single-photon nonlinearities, may enable large-scale ...

Switching From Acceptor to FRET Donor: How the Organic Solar Cell Architecture Can Change the Role of a Chromophore

Advanced Functional Materials, EarlyView.
The non‐fullerene acceptor o‐IDT‐BT‐DCV is used in both binary and ternary blends to investigate the role that it plays in each device architecture. The charge generation pathways are found to differ between the binary and ternary blends with o‐IDT‐BT‐DCV becoming a second donor in the ternary blend.
