Effect of ion temperature on arbitrary amplitude quantum dust ion acoustic solitary waves

Using Sagdeev's pseudopotential technique, the effect of ion temperature and dust density on the arbitrary amplitude dust ion acoustic solitary waves (DIASWs) in quantum electron-ion (e-i) plasma is studied. The effect of ion temperature and dust density on the region of existence, as well as on the shape of the solitary waves are investigated. It is also shown that the quantum parameter H does not play any role in determining the region of existence and on the amplitude of the large amplitude solitary wave. However, H has significant effect on the width of the solitary wave. It is worth noting that our results are in agreement with previous investigations when the effect of ion temperature is neglected.
