properties of the films were determined using Hall measurement system (Van der Pauwconfiguration, Hilton, Australia) at room temperature. Optical absorption studies were carried out by using UV-Vis spectrometer (Cary 100, Varian, Mulgrave, Australia) at room temperature. Photoluminescence (PL) spectra were obtained using a closed-cycle liquidhelium cry generator (APD, SH-4, USA), a spectrometer (
transmission property.
But, Δn is reduced, the non-reciprocal transmission propery disappears.
► Because the nematic liquid crysatal is used as an anisotropic layer(phase retarder layer), Δn can easily be varied by changing applied electircal field.
⇒ Non-reciprocal transmission property + tunable transmitted intensity
∴ optical diode that is electro-tunable
● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for

Ⅰ. 개요
오늘날 서구 학계(특히 사회과학 분야)에서는 질적방법이 점차 수용되고 있다. 이것은 사회의 복잡성이 하나의 관점으로 이해될 수 없음을 연구자들이 자각하게 되었다는 사실에 부분적으로 기인한다. 한국사회과학에서도 이러한 경향은 크게 눈에 띄는 것은 아니라고 하더라도, 양적방법
(4) Double patterning
The double patterning is divided into four parts, leading with wafer requirements and then two sets of lithographic requirements (Generic Pitch Splitting - Double Patterning Requirements Driven by MPU metal Half-Pitch and Generic Spacer Patterning Requirements - Driven by Flash). The lithography requirements are different for each process; the requirements for pitch splitti
