                      semiconductors with prospects for electrical and
                      optoelectronical applications. In this letter, we report on
                      the temperature dependence of the electrical characteristics
                      of high Sn-content Ge0.89Sn0.11 p-i-n diodes. NiGeSn
                      contacts were used to minimize the access resistance and
                      ensure compatibility with silicon technology. The major
                      emphasis is placed on the negative differential resistance
                      in which peak to valley current ratios up to 2.3 were
                      obtained. TCAD simulations were performed to identify the
                      origin of the various current contributions, providing
                      evidence for direct band to band tunneling and trap assisted
                      tunneling.},
