Memory Properties of Ge quantum dots and rings MOS structure prepared by Pulsed Laser Deposition

New memory structures using threshold shifting from charge stored in quantum dots (QDs) and quantum rings (QRs) of Germanium (Ge) are described. The QDs and QRs of Ge were prepared on a p-Si (100) matrix by means of pulsed laser deposition (PLD) using the droplet technique combined with rapid annealing. The perfect planar nanorings with welldefined sharp inner and outer edges were formed via an...

Structure and mechanical properties of low stress tetrahedral amorphous carbon films prepared by pulsed laser deposition

Tetrahedral amorphous carbon films have been produced by pulsed laser deposition, at a wavelength of 248 nm, ablating highly oriented pyrolytic graphite at room temperature, in a 10−2 Pa vacuum, at fluences ranging between 0.5 and 35 Jcm−2. Both (100) Si wafers and wafers covered with a SiC polycrystalline interlayer were used as substrates. Film structure was investigated by Raman spectroscopy...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
