The results of simultaneous measurements of three thermally stimulated phenomena (TSP) are presented as functions of temperature: thermally stimulated exo-electron emission (TSEE), thermally stimulated luminescence (TSL) and thermally stimulated desorption (TSD). These phenomena can be described by similar mathematical relationships. The measurements have been carried out in the temperature range ΔT = -196 to 430 ◦C (ΔT = 77–700 K) under conditions of ultrahigh vacuum (p < 106 Pa). A crystal of the potassium bromide (KBr) was selected to demonstrate the measurements. It becomes evident that some temperature maxima coincide, which evidently suggests a common source of these processes and similar relaxation processes. In particular, the connection of TSEE and TSD in the low-temperature range has not been sufficiently well investigated to date.
