摘要：
A design flaw in a key component of the atomic force microscope (AFM) was discovered. Mechanical principles were used to prove that the popular V-shaped cantilever used in the AFM degrades the performance of the instrument. Calculations established that the simple cantilever design of a straight beam proposed for the original AFM offered improved performance over the V-shape while facilitating calibration and measurement interpretation.
