This paper proposes a new type of substrate for manufacturing LEDs based on AlInGaN heterostructures. Instead depositing SiC layers the surface Si using conventional method, method involving coordinated substitution atoms (MCSA) to form layer is proposed. approach enables growth epitaxial GaN with low defect content and facilitates transfer any surface. The details technology SiC/Si substrates ...

Substrate noise generated by digital circuits on mixed-signal ICs can disturb the sensitiveanalog/RF circuits, such as Low Noise Amplifier (LNA), sharing the same substrate. This paperinvestigates the adverse impact of the substrate noise on a high frequency cascode LNA laid out on alightly doped substrate. By studying the major noise coupling mechanisms, a new and efficientmodeling method is p...

Anisotropic conductive film (ACF) has been used for more than 30 years in flat panel display (FPD) module package. In this paper, the technical trends and development of ACF are described. Among all of them, ACF material design for flexible substrate bonding is critical for the development of flexible display. According to different process flow of flexible AMOLED, flexible substrate bonding te...

in this investigation, fluor-hydroxyapatite (fha) film was deposited on a titanium substrate by sol-gel method. triethyl phosphite, ammonium fluoride and calcium nitrate in ethanol solutions were used respectively as p, f and ca precursors. typical apatite structures were obtained for all coatings after dipping and subsequent heat treatment at 550, 700 and 800 ºc, the coating layers were invest...

a suitable diet and oviposition substrate are two basic needs for successful mass rearing of orius spp. and this may reduce their production costs. the effect of various foods containing eggs of ephestia kuehniella and sitotroga cerealella with various pollens were investigated on the biological parameters of o. albidipennis in the laboratory. moreover, survival, hatching rate and fecundity of ...

in this paper a new uwb textile slot antenna has been designed with high precision. this work aimed to makecloser steps towards real wearability by investigating the possibilities of designing wearable uwb antenna wheretextile materials are used for the substrate as well as the conducting parts of the designed antenna. the antenna iscomposed of three textile layers: the top and bottom are condu...

this study was conducted to investigate the effects of irrigation frequency and substrates on some parameters of greenhouse tomato (cv. hamra) during 1381-1382 at research greenhouse of agriculture college, in ferdowsi university of mashhad. the experiment was based on split plots in the form of completely randomized design and in four replications. irrigation frequency in three levels of 12, 8...

Most P-type ATPases pump specific cations or heavy metals across a membrane to form ion gradients. However, the type IV P-type ATPases evolved the ability to transport specific phospholipid substrates rather than cations and function to establish plasma membrane asymmetry in eukaryotic cells. The mechanism for how a P-type ATPase, or any other transporter, can recognize and flip a phospholipid ...
