Biography
Nadejda Savova Koparanova
(10.08.1930 – 2013)

Born: in Sofia

Education:

    Nadejda Koparanova graduated physics from the Sofia University (1952)

    She was PhD student in the Sofia Technical University (26.11.1953 – 25.11.1956) and defended her dissertation (1960)

    She spoke English, German and Russian well

    She specialised in East Germany (1965, 1966), Russia (1968) and Hungary (1975)

Research:

    Nadejda Koparanova investigated and improved structures of organic layers in xerographic and photodielectric electrophotografic processes

    She investigated electrical properties of xeterogeneous materials and prepared apparatuses for electrophotographic measurements

Professional experience:

    Nadejda Koparanova was teacher on physics at the Second Pholytechnical School in Varna for one year (01.09.1952 – 25.11.1953)
    She became a part time assistant in the Technical University of Sofia (15.09.1959 – 25.10.1960), and senior assistant in the new campus in Darvenitsa (26.10.1960 – 31.10.1963)
    Bulgarian Academy of Sciences appointed her in the Physical Institute (01.11.1963 – 23.06.1975), where she was second rank research assistant
    She became a first rank assistant in the Laboratory of photoelectrical and optical phenomena in wide band semiconductors at the Institute of Solid State Physics, BAS (23.06.1975 – 31.12.1987)
    Koparanova was an organiser of the V²² International Meeting on photoelectrical and optical phenomena in solids
