Opis:
An analysis of the measured macroscopic withinwafer variations for threshold voltage (Vth) and on-current (Ion) over several technology generations (180 nm, 100 nm and 65 nm) is reported. It is verified that the dominant microscopic variations of the MOSFET device can be extracted quantitatively from these macroscopic variation data by applying the surface-potential compact model Hiroshima University STARC IGFET model 2 (HiSIM2), which is presently brought into industrial application. Only a small number of microscopic parameters, representing substrate doping (NSUBC), pocket-implantation doping (NSUBP), carrier-mobility degradation due to gate-interface roughness (MUESR1) and channel-length variation during the gate formation (XLD) are found sufficient to quantitatively reproduce the measured macroscopic within-wafer variations of Vth and Ion for all channel length Lg and all technology generations. Quantitative improvements from 180 nm to 65 nm are confirmed to be quite large for MUESR1 (about 70%) and Lmin(XLD) (55%) variations, related to the gate-oxide interface and the gate-stack structuring, respectively. On the other hand, doping-related technology advances, which are reflected by the variation magnitudes of NSUBC (30%) and NSUBP (25%), are found to be considerably smaller. Furthermore, specific combinations of extreme microscopic parameter-variation values are able to represent the boundaries of macroscopic fabrication inaccuracies for Vth and Ion. These combinations are found to remain identical, not only for all Lg of a given technology node, but also for all investigated technologies with minimum Lg of 180 nm, 100 nm and 65 nm.

Opis:
Water-soluble porphyrin, 5,10,15,20-tetraphenyl- 21H,23H-porphine-tetrasulfonic acid (TPPS), forms J-aggregate in aqueous solution depending on experimental conditions such as pH, dye concentration, and/or ionic strength. The steady-state fluorescence and picosecond single-photon timing spectroscopy were applied for protonated monomer and J-aggregate in aqueous solution and in thin films to reveal the dynamics in the S$\text{}_{2}$ and S$\text{}_{1}$ states. The S$\text{}_{2}$ fluorescence spectra from the protonated monomer and J-aggregate were observed in addition to the normal S$\text{}_{1}$ fluorescence. The lifetime of the S$\text{}_{2}$ state was estimated to be ≈5 ps for J-aggregate, whereas the lifetime is shorter than 1 ps for protonated TPPS monomer. The mesoscopic structures of J-aggregate in thin film with and without polymer on the glass surface were examined by scanning near-field optical microscopy. With the surface topography and scanning near-field optical microscopy transmission images, TPPS J-aggregate was found to form a long and narrow tube-like structure which has a few μm length, 0.2-0.5 μm width, and 5-30 nm height. An unidirectional orientation of the structure was also found, which may be originated from the spin-coating process.

Opis:
Two-dimensional electron gas adjacent to a grain boundary in bicrystal of narrow-gap semiconductor p- Hg$\text{}_{0.79}$Cd$\text{}_{0.19}$Mn$\text{}_{0.02}$Te has been studied under ultra strong impulse magnetic fields (up to 140 T). Both cyclotron resonance and quantum Hall effect are measured for the same samples. The values of the resonance fields point to strong nonparabolicity. A broadening of the line is interpreted in terms of an intersubband mixing that occurs for the upper Landau level. A steep increase in the linewidth in the field range 20-30 T, which coincides with a strong decrease in the Hall resistance is assigned to the field-induced metal-insulator transition in our system.
