Title: The influence of electron irradiation on electron holography of focused ion beam milled GaAs p-n junctions

Abstract

Electron beam irradiation is shown to significantly influence phase images recorded from focused ion beam milled GaAs p-n junction specimens examined using off-axis electron holography in the transmission electron microscope. Our results show that the use of improved electrical connections to the specimen overcomes this problem, and may allow the correct built in potential across the junction to be recovered.

  • Silicon p-n junction specimens have been prepared by focused ion beam milling for examination using off-axis electron holography. By using 28 nS pulsed XeCl excimer laser irradiation we have reduced the total electrically ''inactive'' thickness in these specimens from 142 to 5 nm. A platinum layer has been sputtered onto the specimen surfaces to remove the build up of charge from the region of interest during examination. Subsequently, a value of the built in potential has been determined directly from a phase image which is consistent with theory.
  • The erosion profiles of Cu surfaces after focused ion beam sputtering have been investigated as a function of crystal orientation and ion beam incidence. We find that all patterns are aligned with crystallographic axes and have wavelengths of about 0.5{mu}m. The patterns depend strongly on the crystal orientation, typically with similar patterns for neighboring orientations, but may also be influenced by the ion beam direction. For orientations close to (100), we find however that surfaces stay smooth for all incidence angles. The results are discussed in the context of current continuum models and indicate that modifications to the models aremore » required to account for the effect of crystal orientation.« less
  • Recently we have described a new method for the fabrication of independent ohmic contacts to a two-dimensional electron gas (2DEG) closely separated from an underlying n{sup +} GaAs layer. This was achieved by using molecular beam epitaxial regrowth on an in situ focused ion implanted epilayer. In this article, we present further transport properties of backgated high electron mobility transistors which indicate the versatility of this fabrication technique. Results are presented for two wafers, both with a separation of {approx} 1.38 {mu}m between the backgate and 2DEG: one having a higher carrier concentration, the other a low carrier concentration. Formore » the high carrier concentration wafer, it is shown that up to -7 V could be applied to the backgate at 1.2 K while maintaining leakage currents of <1 nA. Further, in combination with a surface Schottky gate, the onset of second subband occupation was investigated as the 2DEG confining potential was altered. For the low carrier concentration wafer, it is shown that successful backgating action was maintained even when the temperature was increased to {approx} 150K. 6 refs., 4 figs.« less
  • Si nanowires (NWs) with axial p-n junctions were grown by the vapor-liquid-solid method. Transmission electron microscopy and electron holography were used to characterize the microstructure and electrostatic properties. Measurement of the potential profile showed the presence of a p-n junction with a height of 1.0±0.3V. A Schottky barrier was observed at the end of the NW due to the Au catalyst particle. Comparison with simulations indicated dopant concentrations of 1019cm-3 for donors and 1017cm-3 for acceptors. These results confirm the benefit of combining off-axis electron holography with simulations for determining localized information about the electrically active dopant distributions in nanowiremore » structures.« less
