6). Diffusion is the movement of particles under a concentration gradient, that is, from a high-concentration to a low-concentration region. The above diffusion of carriers constitutes the diffusion current and leaves negatively charged acceptor ions on the P-side and positively charged donor ions on the N-side. Thus, an electric field is created around the junction. This electric field is directed from N- to P-side. It sets up an electric current in the reverse direction to the diffusion current flowing under the concentration gradient.

The Néel temperature or magnetic ordering temperature, TN, is the temperature above which an antiferromagnetic material becomes paramagnetic. Superparamagnetism occurs when the material is composed of very small crystallites (1–10 nm). In this case, even when the temperature is below the Curie or Néel temperature (and hence the thermal energy is not sufficient to overcome the coupling forces between neighboring atoms), the thermal energy is able to change the direction of magnetization of the entire crystallite.

To mention a few interesting properties here, for exemplification purpose, nanomaterials offer greater reactivity, optical absorption, catalytic efficiency, super plasticity (the unusual ability of some metals and alloys to elongate uniformly Introduction to Nanosensors 29 by thousands of percent at elevated temperatures) and superparamagnetic characteristics, unique and important aspects of magnetism in nanoparticles. Superparamagnetism is a phenomenon by which magnetic materials may exhibit a behavior similar to paramagnetism even when at temperatures below the Curie or the Néel temperature.
