Electron trapping in low‐density polyethylene

Journal of Polymer Science Part B Polymer Physics (1986)

A. Markiewicz R.J. Fleming

Abstract Thermoluminescence (TL) emission from low‐density polyethylene has been investigated. The glow curves of gas‐free samples x‐irradiated at −190°C and heated to room temperature were found to contain three peaks numbered I, II, and III in order of increasing temperature, in agreement with earlier results. The sites of all traps are accessible to absorbed gases; in the presence of air, O 2 , N 2 or Ar, “gas” traps are formed, resulting in the appearance of an additional peak IV in the glow curve at a temperature between peaks I and II, large reductions in the intensities of peaks II and III, and various changes in peak I. The peak I, II, and III traps are formed from particular chain configurations occurring in the chain‐fold regions of the samples, these configurations being broken up by different forms of molecular motion within the chains. It is unlikely that the peak IV traps are just the gas molecules themselves; they are probably formed from new chain configurations occurring in the amorphous regions of the samples in the presence of the gas, the properties of the gas influencing the associated TL intensity and emission temperature. These traps are also broken up by molecular motion. The samples can be divided into two main types, differing mainly in the height of peak I relative to peak II, which is of nearly constant intensity in all samples. We suggest that two types of trap which are not interconvertible are associated with peak I, and that the dominant type in a given sample depends on the fine details of the sample fabrication process.

Ultrathin high-K gate stacks for advanced CMOS devices

E. P. Gusev D. A. Buchanan E. Cartier Arvind Kumar D. J. DiMaria

Reviews recent progress in and outlines the issues for high-K high-temperature (/spl sim/1000/spl deg/C) poly-Si CMOS processes and devices and also demonstrate possible solutions. Specifically, we discuss device characteristics such as gate leakage currents, flatband voltage shifts, charge trapping, channel mobility, as well as integration and processing aspects. Results on a variety of high-K candidates including HfO/sub 2/, Al/sub 2/O/sub 3/, HfO/sub 2//Al/sub 2/O/sub 3/, ZrO/sub 2/, silicates, and AlN/sub y/(O/sub x/) deposited on silicon by different deposition techniques are shown to illustrate the complex issues for high-K dielectric integration into current Si technology.

Thermoluminescence in polystyrene

Journal of Physics C Solid State Physics (1977)

L. F. Pender R.J. Fleming

An experimental investigation of thermoluminescence glow curves, thermal quenching cycles and isothermal decay plots in polystyrene has been carried out. It is concluded that the luminescence emission process follows first-order kinetics with respect to the concentration of trapped electrons, and that a quasi-continuous distribution of electron trap activation energies exists. The distribution of occupied electron traps immediately after irradiation peaks at 0.08 eV and stretches from a maximum lower bound of 0.05 eV to an upper cut-off of 0.45 eV. The effects of addition of various organic dopants, the application of an electric field, and increasing irradiation dose on the thermoluminescence emission have been investigated.

Radiation-induced suppression of charge injection into low density polyethylene

A. Markiewicz R.J. Fleming

Thermally stimulated conductivity (TSC) and thermally stimulated depolarisation (TSD) current measurements have been used to study the effects of X-irradiation on charge injection into thin films of low density polyethylene. It was found that, for evaporated gold electrodes and a nominal applied field strength of 100 kV/cm, charge injection into an unirradiated sample commences around -50/spl deg/C, passes through a maximum around -20/spl deg/C, falls to a minimum around 0/spl deg/C and then increases rapidly. An X-ray dose of 12 kGy at room temperature appeared to suppress charge injection at temperatures below about 30/spl deg/C. The TSD curves of X-irradiated samples showed a new peak around 90/spl deg/C.

Monte Carlo studies of the excluded volume problem for polymer chains in the continuum. I. Use of inversely restricted sampling techniques

Journal of Physics A Mathematical and General (1975)

Nariida Smith R.J. Fleming

Recent publications on the configurational properties of polymer chains subject to excluded volume restraints, as deduced from studies of off-lattice model chains, are briefly reviewed. It is shown that the data for such models cast doubt on the validity of the frequently quoted equations (RN2)=aN6/5 and (SN2)=a'N6/5 where (RN2) and (SN2) are respectively the mean square end-to-end length and mean square radius of gyration of N-link chains, and a and a' are constants. The use of the technique of inversely restricted sampling to generate off-lattice model chains, with either freely varying or fixed bond angles, and free rotation about bonds, is described.
