  One of the most significant research interests in the field of electronics is
that on quantum dot, because such materials have electronic properties
intermediate between those of bulk semiconductors and those of discrete
molecules. Confinement energy is a very important property of quantum dot. In
this study, quantum confinement energy of a quantum dot is concluded to be
h2/8md2 (d being the diameter of the confinement) and not h2/8ma2 (a being the
radius of the confinement), as reported in the available literature. This is in
the light of a recent study [1]. This finding should have a significant impact
in the understanding of the physics of quantum dot and its technological
application.
