Pinch‐Off Mechanism of High‐Gain Organic Transistors with Field Plates: Statistical Analysis, Device Simulations and Compact Modeling

open access: yesAdvanced Electronic Materials, Volume 12, Issue 4, 18 February 2026.
Statistical analysis of over 3000 devices reveals a novel operating mechanism in printed organic thin‐film transistors featuring a grounded field plate beneath the source. The field plate governs the low and tunable pinch‐off, enabling excellent current saturation and ultra‐high gain.

Radiation‐Induced Degradation and Charge‐Collection Stability in 4H‐SiC p–i–n Betavoltaic Cells

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
4H‐silicon carbide (SiC)–based betavoltaic (BV) cells have gained attention as self‐powered energy sources for long‐term stable operation in space and extreme environments. In this study, a 4H‐SiC p–i–n BV cell was fabricated, and the degradation mechanisms of its electrical characteristics under proton irradiation were investigated.

An E-mode p-channel GaN MOSHFET for a CMOS compatible PMIC [PDF]

open access: yes, 2017
The operation principle of a low power E-mode p-channel GaN MOSHFET is explained via TCAD simulations. The challenges of achieving negative threshold voltage with the scaling of gate length are addressed by adjusting the mole fraction of an AlGaN cap ...

Tuning the Air Stability of N‐Type Semiconductors via Poly(2‐vinylpyridine): The Importance of Humidity and Molecular Weight

open access: yesSmall Science, Volume 5, Issue 12, December 2025.
Blending the n‐type polymer P(NDI2OD‐T2) with hygroscopic poly(2‐vinylpyridine) (P2VP) improves device stability by limiting oxygen diffusion. Higher molecular weight P2VP forms larger domains that absorb moisture, reduce free volume for oxygen, and partition oxygen away from semiconductor crystallites.

Performance Analysis of a Dual‐Drain Dual‐Gate Schottky Tunnel Field Effect Transistor Biosensor for Non‐Ideal Hybridization

open access: yesNano Select, Volume 6, Issue 11, November 2025.
In this study, we analyzed the sensing characteristics of a MoS₂‐based dual‐drain, dual‐gate Schottky tunnel field effect transistor (DD‐DG‐STFET) based on the hybridization process to achieve ground breaking sensitivity. DD‐DG‐STFET sensitivity was calculated by examining steric hindrance across various patterns, including concave and convex, as well ...
