The pressure dependence of the atomic bond lengths and angles of tellurium nanocylinders is investigated by using X‐ray diffraction. Under hydrostatic pressure the nanocylinders exhibit behavior attributed to their nanometer size and cylindrical geometry. Novel compression regimes and fingerprints of isostructural phase transitions are observed that do not exist in bulk tellurium (see figure).
