Abstract Two‐dimensional (2D) nanosheets, which possess atomic or molecular thickness
and infinite planar lengths, are regarded as the thinnest functional nanomaterials. The …

Recent progress in the development of barium strontium titanate thin film varactors for room
temperature tunable microwave devices applications is reviewed, with emphasis on efforts …

Ferroelectric materials are well‐suited for a variety of applications because they can offer a
combination of high performance and scaled integration. Examples of note include …

Capacitors are a mainstay of electronic integrated circuits and devices, where they perform
essential functions such as storing electrical charge, and blocking direct current while …

Recent experimental measurements of large flexoelectric coefficients in ferroelectric
ceramics suggest that strain gradients can affect the polarization and permittivity behaviour …

X-ray analysis of ferroelectric thin layers of Ba 1∕ 2 Sr 1∕ 2 Ti O 3 with different thicknesses
