Embodiments of the present disclosure provide a method to fabricate a hetero-junction in a Tunnel Field Effect Transistor device configuration. An example of this method includes identifying all storage devices in a primary set of storage devices and a first mirror set of storage devices in the array of storage devices. This method embodiment also includes establishing a fluid conduit from a reservoir through the insertion location into the circulatory system of the selected animal by inserting a cannula in fluid communication with the reservoir through the insertion location. The first node may then access the replicas of the first storage object using the respective direct connections to the plurality of nodes. In the optical lens device having two lenses, by disposing the two lenses relative to each other such that the birefringence directions of the lenses form a predetermined angle, preferably 180 degrees, the influence of the birefringence can be reduced as a whole and an optical lens device with a good characteristic can be obtained. One or more addressing electrodes are in electrical contact with each plasma-shell.
