2,3 차원경계 두께의 poly (vinylidene fluoride trifluoroethylene) Langmuir Blodgett 박막으로부터 전기광학 특성을 연구하였다. 20nm 두께 이하의 박막들로부터 한계 크기 효과 (finite size effect)가 상실되는 것을 관측하였으며, 이로부터 이 박막들이 2차원특성의 강유전체 박막임을 확인하였다. 10층의 박막을 열처리하여 최대의 전기광학상수를 구했으며 그 값은 26 pm/V였다. 10층 두께 주위에서 전기광학효과의 크로스오버와 열처리 후의 나노메사의 형성에 대해 논의하였다.

The electro-optic properties in Langmuir Blodgett films of poly (vinylidene fluoride trifluoroethylene) are investigated in the crossover region between two and three dimensions. The absence of finite size effect is observed in the films thinner than 20 nm, which confirms that these films are two dimensional ferroelectrics. The copolymer LB film of P(VDF-TrFE) exhibits the largest electro-optic response(26 pm/V) at 10 layer thickness. The cross-over behavior of electro-optic effect around the 10layer thickness was discussed with the formation of nanomesa after thermal annealing.
