Shri Krishna Joshi is am India
n physicist
. He was born on June 6, 1935 in the village of Anarpa in Kumaun, Uttarakhand
, India.
in 1962. Joshi's broad areas of interest are condensed matter
and collision
processes. His early research was in the study of phonon
s in metals and insulators. Later, he studied electronic states in disordered systems and electron correlation in narrow band solids. He has also worked on surface states and surface segregation. Joshi conducted studies on excitation and ionization
processes in atoms, ions, and molecules. His current research interests lie in strongly correlated electron systems, such as high temperature superconductors, and also in nanotechnology
, especially electron transport in quantum dot

Quantum dot
A quantum dot is a portion of matter whose excitons are confined in all three spatial dimensions. Consequently, such materials have electronic properties intermediate between those of bulk semiconductors and those of discrete molecules. They were discovered at the beginning of the 1980s by Alexei...
