== Biography ==<br />
A. P. B. Sinha, born on 27 December 1928, joined the [[University of London]] from where he secured a PhD in 1954; his thesis was based on solid state chemistry.<ref name="Indian fellow" /> Later, he served the [[National Chemical Laboratory]], Pune as a director's grade scientist and headed the Physical Chemistry division of the institution. Continuing his researches on solid state chemistry, Sinha studied low mobility semiconductors with respect to its electron transport and crystal distortions caused by electron lattice transitions, switching, magnetic ordering and memory effects. He is known to have synthesized new manganites and reportedly developed a number of solid state products such as [[thermistors]], photocells, magnets and photovoltaic products. Based on his studies on electron lattice interaction, Sinha proposed support theories for the [[ferroelectricity]] theory and developed new theories on the ''thermoelectrical power and mobility in semiconductors''.<ref name="Handbook of Shanti Swarup Bhatnagar Prize Winners">{{cite web | url=http://www.csirhrdg.res.in/ssb.pdf | title=Handbook of Shanti Swarup Bhatnagar Prize Winners | publisher=Council of Scientific and Industrial Research | date=1999 | access-date=October 5, 2016 | pages=34 | archive-url=https://web.archive.org/web/20160304043957/http://www.csirhrdg.res.in/ssb.pdf | archive-date=March 4, 2016 | url-status=dead }}</ref> His researches are reported to have widened the understanding of conduction in semiconductors.
