MBE‐Grown ScAlN‐on‐Si Films: Enhancing In‐Plane Crystallinity for Extensional Mode BAW Resonators

Advanced Electronic Materials, EarlyView.
The achievement of in‐plane single crystallinity and a high piezoelectric modulus in epitaxially grown ScAlN films on AlN‐buffered Si (111) enables extensional mode ScAlN‐on‐Si bulk acoustic wave (BAW) resonators with an ultra‐high Q of ≈97k at 70.28 MHz, resulting in a frequency‐Q product of ≈6.86 × 1012, suitable for emerging wireless technologies ...

Multiferroicity in Calcium Manganate via Strain Engineering

Advanced Electronic Materials, EarlyView.
Multiferroicity is achieved in the non‐ferroelectric magnet calcium manganate through tensile‐strain engineering. The ferroelectricity below 45 K is evidenced by the polarization‐electric field hysteresis loops, and the magnetization below 125 K is confirmed by the magnetization measurements.

The Role of Thermally Activated Charge Separation in Organic Solar Cells

Advanced Energy Materials, EarlyView.
Charge separation mechanism in state‐of‐the‐art system has been a part of intense debate. Here, it is presented that as, the system moves toward the low‐offset regime the thermal contribution plays an important role to derive the charge separation. The rational guide is provided to achieve the maximum CSE and maximum VOC simultaneously within the mid ...

Langmuir‐Type Build‐Up of Self‐Generated Interlayers in Organic Solar Cells

Advanced Energy Materials, EarlyView.
Metal‐induced migration of polyethylene glycol (PEG) oligomer additives to Al contacts follows a Langmuir‐like adsorption behavior forming interfacial dipole layers. Consistent Voc‐concentration trends across various additives in two distinct organic solar cell systems demonstrate the generality of the phenomenon.
