Magnetic and electric properties of transition-metal-doped ZnO films
TL;DR: In this article, a 3d transition metal-doped ZnO films (n-type Zn1−xMxO) were formed on sapphire substrates using a pulsed-laser deposition technique, and their magnetic and electric properties were examined.
Journal ArticleDOI
Ferromagnetism in LaFeO3-LaCrO3 Superlattices
TL;DR: Ferromagnetic spin order has been realized in the LaCrO3-LaFeO3 superlattices and ferromagnetic ordering has been achieved in Fe3+ and Cr3+ layer along the [111] direction.
Journal ArticleDOI

TL;DR: In this article, field effect transistors (FETs) with gate lengths of 0.1 /spl mu/m were fabricated using polycrystalline chemical-vapor-deposited diamond films with large grains.
Journal ArticleDOI
Fabrication of the low-resistive p-type ZnO by codoping method
TL;DR: In this paper, the p-type ZnOfilms were fabricated by passing N 2Ogas through an electron cyclotron resonance (ECR) or RF plasma source.
Journal ArticleDOI
