In a machine for driving screw anchors and other foundation components, a desired embedment depth is calculated based on a minimum required embedment depth, work point height and length of available upper leg sections. Once calculated, the machine automatically drives the screw anchor to the depth so that one of the available upper leg lengths will fit between the driven screw anchor and apex truss hardware. If a secondary condition is satisfied that guarantees sufficient pull-out strength, a new upper leg length may be selected and the driving operation terminated prior to reaching the desired embedment depth, reducing the amount of material necessary to construct the truss foundation.

Continuous miniaturization of semiconductor devices is the key to boosting modern electronics development. However, such downscaling strategy has been rarely utilized in photoelectronics and photovoltaics. Here, in this work, a full-vdWs 1D p-Te/2D n-Bi2O2Se heterodiode with a rationally-designed nanoscale ultra-photosensitive channel is reported. Enabled by the dangling bond-free mixed-dimensional vdWs integration, the Te/Bi2O2Se type-II diodes show a high rectification ratio of 3.6×104. Operating with 100 mV reverse bias or in a self-power mode, the photodiodes demonstrated excellent photodetection performances, including high responsivities of 130 A W−1 (100 mV bias) and 768.8 mA W−1 (self-power mode), surpassing most of the reports of other heterostructures. More importantly, a superlinear photoelectric conversion phenomenon is uncovered in these nanoscale full-vdWs photodiodes, in which a model based on the in-gap trap-assisted recombination is proposed for this superlinearity. All these results provide valuable insights in light-matter interactions for further performance enhancement of photoelectronic devices.
