Electronics of Compound Materials Nanosheets

12 Materials for Spin Electronics

Materials which are currently used in spin electronic devices, and materials which may be useful in future are discussed. These include ironcobaltand nickel-based alloys for spin polarization and analysis, metallic and insulating antiferromagnets for exchange bias and oxides for tunnel barriers. The 3d alloys also serve as detection or sensor layers. Permanent magnet materials play a role in bi...

Controlled doping of semiconducting titania nanosheets for tailored spinelectronic materials.

Ti₁-x-yFexCoyO₂ nanosheets are synthesized in which the (Fe/Co) content is systematically controlled in the range of 0 ≤ x ≤ 0.4 and 0 ≤ y ≤ 0.2. A key feature of this new preparation is the use of (Li/Fe)-, (Fe/Co)- and (Li/Co)-co-substituted layered titanates as starting materials. In exfoliated nanosheets, the composition can be intentionally modified by controlled Fe/Co substitution into Ti...

Materials Meets Concepts in Molecule-Based Electronics

Molecular semiconductors differ from traditional semiconducting materials (such as Ge, Si, GaAs, etc.) in many regards including their mechanical, electrical, and optical properties, which is a direct consequence of their construction principles. While in traditional semiconductors, the basic building blocks are atoms that are strongly linked together by covalent or ionic bonds, organic semicon...

Pyrene-based materials for organic electronics.

Materials for bioresorbable radio frequency electronics.

Materials, device designs and manufacturing approaches are presented for classes of RF electronic components that are capable of complete dissolution in water or biofluids. All individual passive/active components as well as system-level examples such as wireless RF energy harvesting circuits exploit active materials that are biocompatible. The results provide diverse building blocks for physic...
