Papers on the Applied Physics Letters

I've found some interesting paper on this month's issue:

Estimation of electron traps in carbon-60 field-effect transistors by a thermally stimulated current technique, by Toshinori Matsushima, Masayuki Yahiro, and Chihaya Adachi

Ballistic quantum transport in a nanoscale metal-oxide-semiconductor field effect transistor, by Vijay K. Arora, Michael L. P. Tan, Ismail Saad, and Razali Ismail

Tuning of electrical characteristics in networked carbon nanotube field-effect transistors using thiolated molecules
, by Chun Wei Lee, Keke Zhang, H. Tantang, Anup Lohani, S. G. Mhaisalkar, Lain-Jong Li, T. Nagahiro, K. Tamada, Y. Chen

These are three quite different topics, but I think that they are interesting enough.

IEEE Awards

I've just received the list of the 2007 IEEE Awards, and I wanted to make a comment. First of all, many congratulations to dear Prof. Michael S. Shur, for his two (yes, TWO) awards. The first award is the Leon K. Kirchmayer Graduate Teaching Award, that goes to those able to show inspirational guidance of graduate students in all IEEE fields of interest. Prof. Shur obviously is a most than adequate recipient for this award. His second award (jointly with Arturas Zukauskas) is the Donald G. Fink Prize Paper Award, and goes to the authors of the most outstanding paper published by the IEEE.

I also want to congratulate Prof. Yannis P. Tsividis, who is the recipient of the 2007 Gustav Robert Kirchhoff Award, that goes to those providing outstanding contributions to the fundamentals of any aspect of electronic circuits and systems that has a long-term significance or impact. Again, Prof. Tsividis is a mythical figure in the field of Device Modeling.

In brief, many congratulations for them and for all the other recipients of the IEEE Awards!

Free Keithley Web Seminar on Measurement

This seminar covers precision test and measurement applications for an emerging class of low cost (<$1000 USD) 6½-digit digital multimeters. Learn how to assemble a testing error budget for various applications for electronic devices and products. Examples include simple test programming to support automatic acquisition and evaluation of measurement data, as well as basic front panel operation.

By participating in this seminar, you will learn and understand:

  • How to establish a measurement accuracy budget for an application
  • How to account for central and parasitic sources of error
  • How to match your accuracy requirements with the appropriate DMM
  • How to calculate system test uncertainties and errors

This seminar is recommended for development and test engineers and scientists who need to make high precision electrical measurements using widely available, highly accurate 6½-digit DMMs.

About the Presenter:

Chuck Cimino is the Marketing Director for Multi-Application Instruments at Keithley Instruments, Inc. in Cleveland, Ohio. He joined Keithley Instruments in 1981 and has held many positions, including Test Engineer, Design Engineer, Project Manager, and Product Marketer.
The seminar will be broadcasted over the internet and requires your registration prior to the event.

When is it?

Europe: Thursday, September 13, 2007
15:00 Central European Time
(UTC/GMT: 13:00)

Agilent Announces New HVMOS Package For IC-CAP Software

I copy part of the press release (please note the language they use):

Agilent Technologies Inc. announced the availability of a new parameter extraction solution for high voltage (HV) complementary metal oxide semiconductor (CMOS) devices used in a range of automotive and consumer products, as well as LCD and display driver applications. The HVMOS extraction package, for use with Agilent's Integrated Circuit Characterization and Analysis Program (IC-CAP) software platform, enables engineers to model HV CMOS devices using Synopsys' HSPICE simulator, HVMOS Level 66 compact model.

Implemented as a compact model in HSPICE, HVMOS Level 66 compact model outperforms most other HVMOS model solutions in speed and convergence. The HVMOS model includes all relevant physical effects unique to high-voltage operation, including symmetric and asymmetric source and drain resistances, quasi-saturation, transconductance fall off at high-gate voltage, and self-heating effects. As a result, it allows HV CMOS devices to be modeled with unparalleled DC and capacitance modeling accuracy and simulation speed. HVMOS models are used by both analog and digital designers during circuit simulation.

Statistical simulation of memories

In the last issue of electronics letters (August 2 2007, vol 43, issue 16), there is an interesting paper on statistical simulation of sub-100nm memories. Here you have the link to the abstract, and try to have a look at it. I think that this (I mean: incorporating statistical techniques into the whole model) is an issue for a good compact model to be accepted by the design community.
Otherwise, if there is no way to take into account the huge variations in modern technologies, the model will be quite useless for them.

Scaling effects on short-channel organic transistors

If you are interested in organic transistors, perhaps you will appreciate having a look at the paper "Scaling effect on the operation stability of short-channel organic single-crystal transistors", appeared in the Applied Physics Letters of 6 August 2007 (link).
As they say in the abstract: "Organic single-crystal transistors allowed the authors to investigate the essential features of short-channel devices. Rubrene single-crystal transistors with channel lengths of 500 and 100 nm exhibited good field-effect characteristics under extremely low operation voltages, although space charge limited current degrades the subthreshold properties of 100 nm devices. Furthermore, bias-stress measurements revealed the remarkable stability of organic single-crystal transistors regardless of device size. The bias-stress effect was explained by the trapping of gate-induced charges into localized density of states in the single-crystal channel."
