A particle has a permanent dipole moment, a film includes the particle, and a method of forming the film includes aligning the particle on a surface. The particle has a permanent dipole moment and includes heterogeneous materials, wherein a positive pole is located in a first material and a negative pole is located in a second material different from the first material. The method includes aligning a particle such that the particle has one dipole moment direction. The film includes the aligned particles.

Particles having permanent dipole moment, films including the particles, and methods of preparing the films

A method of manufacturing a quantum dot layer, and a quantum dot optoelectronic device including the quantum dot layer. The method includes sequentially stacking a self-assembled monolayer, a sacrificial layer, and a quantum dot layer on a source substrate; disposing a stamp on the quantum dot layer; picking up the sacrificial layer, the quantum dot layer and the stamp; and removing the sacrificial layer from the quantum dot layer using a solution that dissolves the sacrificial layer.
