Probing "Memristors" with X-Rays
Scientific Achievement

"Memristor" (memory resistor):

With powerful x-ray microscopy techniques, researchers
probed memristor devices to learn about their local chemistry,
structure, and elemental mapping.

Significance and Impact

A circuit element that increases
or decreases its resistance
depending on which way current
flows, retaining its last resistance
level when current is stopped and
restarting at that level when current
resumes.

Energy-efficient computers with high memory retention;
strong alternative to flash memory; reproduces properties of
neurons ("neuristors").

Research Details

Soft x-ray scanning transmission x-ray microscopy (STXM) was done on
TiO2 at ALS Beamlines 5.3.2 and 11.0.2.
Found a region where oxygen vacancies had condensed and ordered
to form Ti4O7 (Mgneli phase).
Learned key mechanisms for switching memristors (electrochemistry,
thermal processes).
An insulator-to-metal transition occurs in the Mgneli phase when
heated; an insight in the development of the neuristor.
J.P. Strachan et al., Adv. Mater. 22, 3573 (2010); J.P. Strachan et al., Nanotechnology 22, 254015 (2011).
Work was performed at Lawrence Berkeley National Laboratory, ALS Beamlines 5.3.2 and 11.0.2. The
operation of the ALS is supported by the U.S. Department of Energy, Office of Basic Energy Sciences.

STXM images of titanium dioxide, a
memristor material. These measurements provide researchers with
chemical and structural information
and show how resistance-switching
leads to new material phases within
the device.
