Summary on Grant Application Form
The split gate transistor was invented 22 years ago and has ben in wide-spread use ever since in the investigations of the fundamental physics of electron transport in low-dimensional structures. At most a few such transistors have ben used in very small circuits. We have devised a way of making over 1000 split gate devices on the same chip and the way to bias each gate, while needing only 40 contacts to read out the transport properties of the entire array. This advance will greatly accelerate both the physics investigations and the exploration of new device concepts, taking fully into account a statistical analysis of the results as a function of the intrinsic fluctuations from gate-to-gate.
