41. Delineation of pn Junctions by Scanning Tunneling Microscopy/Spectroscopy in Air and Ultra High Vacuum
Published: 6/1/1995
Authors: Richard M Silver, John A. Dagata, W. F. Tseng
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=29181

42. Delineation of pn Junctions by Scanning Tunneling Microscopy/Spectroscopy in Air and Ultrahigh Vacuum
Published: 5/1/1995
Authors: Richard M Silver, John A. Dagata, H. W. Tseng
Abstract: Lateral dopant profiling of cleaved, passivated abrupt GaAs pn junctions using scanning tunneling microscopy/spectroscopy is demonstrated both in ultrahigh vacuum and air. A combination of forward-and reverse-bias imaging and position-dependent tunn ...

44. SPM-Based Lithography for Electronics Device Fabrication: New Strategies and Directions
Published: 1/1/1995
Author: John A. Dagata
Abstract: Direct patterning of a semiconductor surface to produce an ultrathin oxide mask has proven to be a promising approach for integrating lithographic methods based on scanned probe microscopy (SPM) into existing electronics device processing. The result ...

47. Ambient and Vacuum Scanning Tunneling Spectroscopy of Sulfur and Oxygen-Terminated Gallium Arsenide
Published: 11/1/1994
Authors: Richard M Silver, John A. Dagata, H. W. Tseng
Abstract: Tunneling spectroscopy of sulfur- and oxygen-terminated n- and p-type GaAs (110) surfaces is reported for air and ultrahigh-vacuum conditions. Simulations of the complete I-V characteristics with explicit inclusion of surface states within the planar ...

49. Photoreflectance Study of the Chemically Modified (100) GaAs Surface
Published: 5/1/1994
Authors: John A. Dagata, O Glembocki, J Tuchman, K Ko, S Pang
Abstract: Photoreflectance (PR) spectroscopy has been used to study the Fermi-level pinning position of chemically modified (100) GaAs surfaces. It is shown that there are two pinning positions for the unmodified (100) GaAs surface. For n-GaAs, the Fermi level ...
