    Individualization of patients for adjuvant chemotherapy after surgical treatment of cervical cancer (1987)

    Notes: Summary. Adjuvant chemotherapy using Tegafur (l-(2-tctra hydrofuryl)-5-fluorouracil) was given to 52 of 216 patients with recurrence risk of cervical cancer after primary surgical treatment, the degree of risk of recurrence having been formulated as a discriminant function by computer analysis of risk factors involved in disease recurrence. Using the formula, we have managed outpatients in three groups—no recurrence and recurrence after, and before 5 years. Under existing circumstances the power of the discriminant function we have achieved is not yet entirely satisfactory although clinically of value in patient management. Oral, long-term adjuvant chemotherapy in risk groups was of value, with a 37.4% instantaneous recurrence rate and mild side-effects. An instantaneous recurrence rate of 37.4% signifies that the recurrence rate in the group of patients given chemotherapy would be 37.4% if it were 100% in the patients not so treated—an improvement factor of just less than 3.

    Novel slip-free rapid thermal annealing of GaAs in vacuum with excellent uniformity and reproducibility (1991)
    [S.l.] : American Institute of Physics (AIP)

    Notes: This paper describes novel rapid thermal annealing for GaAs wafers under vacuum conditions (VRTA) using a three-zone lamp power control method. The developed RTA technology eliminates generation of crystallographic slip lines and wafer deformation due to the convection effect caused by ambient gas. A three-zone lamp power control method produced excellent uniformity in the activated layer, presenting the best data ever attained by RTA. Also, numerical simulation demonstrates improved temperature uniformity achieved by a three-zone lamp power control method which reduces the edge radiation effect. Moreover, we have found that VRTA technology is particularly effective for annealing large-size GaAs wafers, which are more easily deformed or slip-lined than 2-in. wafers. We have applied VRTA to fabricating ion-implanted n+ contact regions for self-aligned 0.5-μm-gate doped-channel hetero-metal-insulator-semiconductor field-effect transistors with a lightly doped drain, and have obtained excellent Vt uniformity, σVt=19 mV, on a 2-in.-diam wafer. These features, together with a simple wafer-supporting method, using several quartz pins, cause the improved VRTA technology to provide high throughput and production yield for high-performance short-gate GaAs integrated circuits.

    Atomic-scale formation of ultrasmooth surfaces on sapphire substrates for high-quality thin-film fabrication (1995)

    Notes: The atomically ultrasmooth surfaces with atomic steps of sapphire substrates were obtained by annealing in air at temperatures between 1000 and 1400 °C. The terrace width and atomic step height of the ultrasmooth surfaces were controlled on an atomic scale by changing the annealing conditions and the crystallographic surface of substrates. The obtained ultrasmooth surface was stable in air. The topmost atomic structure of the terrace was examined quantitatively by atomic force microscopy and ion scattering spectroscopy as well as a theoretical approach using molecular dynamics simulations. © 1995 American Institute of Physics.

    Determination of the crystal orientation of CuInSe2 by Raman spectroscopy (1993)
    [S.l.] : American Institute of Physics (AIP)

    Notes: We have developed a new method for the determination of the crystal orientation of CuInSe2 by Raman spectroscopy. The single crystal of CuInSe2 has a (112) natural surface. On this surface we often observe slip lines, which construct a triangular shape. However, it is difficult to identify which corner is the projection of the c axis. We established a new method to identify the c direction by using Raman spectroscopy. This method is also effective for small single crystals down to the size of 1 μm.

    Hysteresis of the work function of Co(0001) surface resulting from an allotropic transformation (1992)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The influence of the crystallographic phase transformation on the work function was studied on a Co(0001) surface by a precise measurement of the contact potential difference. The characteristic hysteresis of the work function due to the hcp(arrow-right-and-left)fcc allotropic transformation was found. The work function changes abruptly by about 2 meV with the phase transformation while decreasing monotonically with temperature except in the transformation range. The contributions of the surface dipole barrier and the chemical potential of electrons to the work function are discussed from the point of view of cellular approximation.

    Notes: An automated ac susceptibility measuring system based on an ac mutual inductance bridge is described. A personal computer and a digital-analog converter are used to control the amplitude and phase of the compensatory signal which balances the bridge. An analog multiplier and a variable-resistance photocoupler are used in the amplitude and phase control circuits, respectively. The magnetic moment of a sample for a 1-μV output voltage is 3.8×10−6 emu/μV. Sufficient sensitivity was confirmed for an application to oxide superconductors.

    Simulation studies of heavy ion heating by current-driven instabilities (2000)

    Notes: Nonlinear evolution of current-driven instabilities and associated energy transport among different particle species are studied by means of a two-dimensional, electrostatic, particle simulation code with full ion and electron dynamics. The plasma is assumed to consist of hydrogen (H) and helium (He) ions and electrons with the electron temperature larger than the ion temperatures; the electrons drift along a uniform magnetic field with an initial speed equal to the thermal speed. Then, simulations show that after the development of ion acoustic waves and fundamental H cyclotron waves, second harmonic waves are destabilized due to the change in the electron velocity distribution function parallel to the magnetic field, fe(v(parallel)). Even though the linear theory based on the initial conditions predicts that the second harmonics are only marginally unstable, they eventually grow to the largest amplitudes and heat He ions more significantly than H ions. The instabilities of these three kinds of modes with different phase velocities give rise to flattening of fe(v(parallel)) over a region larger than the thermal speed. © 2000 American Institute of Physics.
