Fri Jul 22 15:22:51 PDT 2005


The Summer Undergraduate Research Fellowship Program in Information
Technology (SURF-IT) presents the second in its four-part summer seminar
series, featuring faculty projects involving SURF-IT students.

The seminar session will include a light lunch, served at 11:45 a.m.,
and two 20-minute research talks.

    The session will be held:

    July 26, 2005   (Tuesday) 

    Calit2 Building, Room 3008

==============================================

Noon  

Speaker:  	Jia Grace Lu
		Assistant Professor
		Chemical Engineering & Materials Science
		
Title:  "Semiconducting Nanowires as Nanoelectronic Building Blocks"

Abstract:  In general, this project incorporates fundamental science and
technological application of nanostructured materials, with the aim to
build integrated nanoscale devices crucial for future information
technology, fitting with the vision of Calit2.  This work focuses
particularly on the electrical, optical, magnetic and chemical sensing
properties of individual single-crystal semiconducting nanowires,
configured as field effect transistors.  They demonstrate enhanced
transistor property with large on-off ratio, strong
polarization-dependent photoconductivity, and high sensitivity to toxic
gases such as NO2, NH3, and CO.  At present, we are working to obtain
n-type and p-type metal-oxide nanowires with uniform electrical
properties, and fabricating vertically aligned field effect transistors
and logic gates in order to fully utilize the scaling advantage of these
nanomaterials.  In addition, magnetic doping in the nanowires is being
explored to study low-dimension ferromagnetic ordering and to develop
efficient spin injectors and spin transistors.  The objectives of the
student's project are to understand the effect of reduced dimensionality
on the properties of semiconductors; and to design, create, and
characterize coupled nanostructures. 

	Undergraduate Researcher:  Lei Huang


==============================================

12:30 p.m.

Speaker: 	Simon Cole
		Assistant Professor
		Criminology, Law, & Society

Title:  "Fingerprint Data Collection and Analysis"

Abstract:  This talk will cover current controversies over the
reliability of forensic fingerprint identification, focusing on the role
that automated fingerprint identification systems are playing in this
controversy and what role they might play in the future.  The speaker
will briefly discuss, and solicit comments on, research being carried
out this summer using an automated fingerprint identification system.
  
	Undergraduate Researcher:  Robert Carpenter

Future seminars will be held August 9 and August 23.
