Alan Jay Heeger (born January 22, 1936) is an American physicist, academic and Nobel Prize laureate in chemistry. Heegar was elected as a member into the National Academy of Engineering in 2002 for co-founding the field of conducting polymers and for pioneering work in making these novel materials available for technological applications.
The two developed the electrical conductivity of polyacetylene along with American physicist Alan Heeger. [3] [4] In 1977 they discovered that doping with iodine vapor could enhance the conductivity of polyacetylene. The three scientists were awarded the Nobel Prize in Chemistry in 2000 in recognition of the discovery.
Polythiazyl caught Heeger's interest as a chain-like metallic material, and he collaborated with Alan MacDiarmid who had previous experience with this material. By the early 1970s, this polymer was known to be superconductive at low temperatures. [9] Shirakawa, Heeger, and MacDiarmid collaborated on further development of polyacetylene. [8]

Among the 892 Nobel laureates, 48 have been women; the first woman to receive a Nobel Prize was Marie Curie, who received the Nobel Prize in Physics in 1903. [12] She was also the first person (male or female) to be awarded two Nobel Prizes, the second award being the Nobel Prize in Chemistry, given in 1911. [11]

He then went to the Institute for Polymers & Organic Solids at the University of California, Santa Barbara, California, United States, where he worked for four years and, together with Alan J. Heeger (Nobel Prize in Chemistry, 2000) discovered and investigated the polymeric organic solar cells has (1992–1996). In April 1996, he accepted the ...
