Effects of Impurities in Polyacetylene : Site-Type Short-Ranged Impurities

スポンサーリンク

概要

• 論文の詳細を見る

• Effects of impurities in polyacetylene are investigated numerically by using Su-Schrieffer-Heeger's model with short-ranged site-type impurities. Particular em-phases are on the infrared activities. The change of the total electron number, due toimpurity doping, is compensated by introducing the same numbers of positive andnegative dopants. Soliton formation and its pinning due to the impurities are con-firmed. The amplitude oscillation mode, localized around a soliton, is found to havea possibility to become infrared active, though it is not active without impurities.
