Abstract: Interatomic forces are measured with subatomic lateral resolution by in situ calibrated non-contact and passively thermal drift compensated atomic force microscopy in aqueous or generally liquidous environment; interatomic forces acting between distinct electronic orbitals of front-most tip atom and opposing sample atom can be quantitatively measured with subatomic lateral resolution. Calibration standard is a CaCO3-crystal, which undergoes a well defined pressure induced phase transition from the calcite to the aragonite crystal lattice structure providing an accurate independent force anchor point for the AFM's force versus distance curve. Furthermore, an independent actual tip-sample-distance d calibration is obtained by directly observing oscillatory (steric) solvation forces originating simply from packing effects of the liquid particles at very small tip-sample separations d.

Abstract: One, several or very many parallel quantum wires, e.g. especially 1-dimensional quantum-conducting heavy ion tracks—“true” quantum wires at room temperature—see similarly EP1096569A1 [1] and [2], or also perhaps SWCNTs, vertically directed or also slightly tilted—up to about 45 degrees—arranged in a 2 dimensional plane, which as a 2-dimensional array interconnect the source and drain contacts of the here invented transistor, are modulated with respect to their quantum-mechanical conductivity via the strength of an applied electric or magnetic field [3], which is homogenous or variable in space locally across the 2 dimensional quantum wire array. The I-V curves of such quantum wires are measured via a double resonant tunnelling effect which allows identifying quantum effects at room temperature. A “true” quantum wire is characterized by quantized current steps and sharp current peaks in the I-V (Isd versus Usd, not just Is a versus Ugate) curve.
