There are two main approaches to synthesize nanomaterial or nanoparticle. One is top-down approach and another is the bottom-up approach. Let us discuss these approaches
Definition of quantum dots: If all the three dimensions of a material are reduced to nano range, then the nanomaterial or the structure is called
Definition of quantum wire: If the two dimension of the material are reduced to nano range while the third dimension remains large, then the material
Definition of quantum well: If one dimension of the material is reduced to nano range while the other two dimensions remain large, then the material
Electron confinement or quantum confinement is another process that occurs in nanoparticles. We know that when atoms are isolated, then their energy levels are discrete
Surface area to volume ratio in nanoparticles have a significant effect on the nanoparticles properties. Firstly, nanoparticles have a relative larger surface area when compared
To answer the question that what is nanotechnology, let us first discuss nanoscale because nanotechnology is a science that deals with objects in nanoscale. Nano
