The features of conductometric gas sensors based on metal oxide composites are
considered. The methods of the composites forming and the advantages of their using in the …

The semiconductor ZnO has gained substantial interest in the research community in part
because of its large exciton binding energy (60 meV) which could lead to lasing action …

ZnO nanoparticles are still a hot area for research even after ample work has been done by
researchers across the world. It is a versatile material for doping of different transition metals …

ZnO is a unique semiconductor that used for various applications. The preparation method,
crystal morphology and particle size have important role in its physical properties. This …

Although high-entropy alloys have been intensively studied in the past decade, there are still
many requirements for manufacturing processes and application directions to be proposed …

This review article first presents a summary of current understanding of the magnetic
properties and intrinsic ferromagnetism of transition-metal (TM)-doped ZnO films, which are …

Room-temperature ferromagnetism is observed in (110) oriented ZnO films made from
targets containing 5 at.% of Sc, Ti, V, Fe, Co, or Ni, but not Cr, Mn, or Cu ions. There are …

Cobalt doped zinc oxide nanoparticles (NPs) and nanorods (NRs) were synthesized by a
simple chemical method. An increase in the formation of nanorods with an increase in cobalt …

The observation of ferromagnetism in magnetic ion doped II–VI diluted magnetic
semiconductors (DMSs) and oxides, and later in (Ga, Mn) As materials has inspired a great …

We report on the high-temperature ferromagnetism in Co-doped ZnO films fabricated by the
sol–gel method above 350 K. The lattice constant of c axis of wurtzite Zn 1− x Co x O follows …
