optical microscopes can be very simple, although there are many complex designs which aim to improve resolution and sample contrast.
1. The type of Optical microscope
1) Bright-field microscopy
Bright-field microscopy is the simplest of all the optical microscopy illumination techniques. Sample illumination is transmitted white light and contrast in the sample is caused by absorbance of
(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

NEC는 최근 카본나노튜브(이하 CNT)의 한 종륲인 카본나노혼(CNH)을 촉매담지전극에 사용하므로써 이와 같은 휴대용 연료전지의 성능을 향상시킬수 있음을 보였다.
카본나노튜브는 1991년에 이이지마에 의해 발견된 것으로 지금은 나노기술의 대표적인 소재로서 세계의 주목을 받고 있다. 그 한 종류
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 (f = 0.5 m, Acton Research Co., Spectrograph 500i, USA) and intensified photodiode array detector (Princeton Instrument co., IRY1024, USA)
